What Are Silicone Rubber Gaskets?
Gaskets are mechanical seals used to fill in the spaces between two mated surfaces. They are engineered to prevent fluids (gas or liquid) from leaking out of or into the system between the two surfaces while under compression. In some assemblies, they serve as a barrier that keeps two components separated to protect them against friction damage.
These sealing devices can be made from a wide range of materials depending on the requirements and restrictions of the application. One of the most commonly used is silicone rubber. It exhibits many advantageous characteristics that make it suitable for various industrial and commercial applications. For example, its excellent resistance to extreme temperatures, ozone, and ultraviolet (UV) radiation enables it to be used in outdoor environments without fear of premature degradation.
Types of Silicone Gasket Materials
Silicone rubber comes in many types, grades, and forms to suit different applications. The ones commonly used to make gaskets are:
- Solid silicone rubber. This material has a dense molecular structure. It can have low or high durometers. The former is suitable for seals with low closure force requirements, while the latter is suitable for seals with high closure force requirements.
- Sponge silicone rubber. This material has a cellular structure that provides some cushioning and padding properties. It is available in two basic types: open-cell and closed-cell. Open-cell sponge silicone has interconnected pockets that allow air, chemicals, and water to pass through when it is uncompressed. Closed-cell sponge silicone has pockets that are filled with nitrogen to prevent anything from passing through it.
- Foam silicone rubber. This material offers flame resistance. It is available in soft, medium, firm, and extra-firm grades and open-cell, closed-cell, and combined open-cell/closed-cell variations.
- Liquid silicone rubber (LSR). This material is a two-part material system that must be mixed and heat cured before use. It offers fast and inexpensive molding operations, clean curing operations, and low durometer options.
These silicone rubber gasket materials can be made in various grades, such as FDA-compliant, UL-compliant, and MIL-SPEC, and shaped into sheet, roll, and other standard or custom profile forms to meet different industry and application requirements.
Why Use Silicone Rubber?
Silicone rubber exhibits many properties that make it ideal for use in gaskets, such as:
- Resilience over a broad temperature range. Silicone rubber is resistant to chemicals, moisture, oxygen, ozone, and sunlight, and it maintains these qualities in both extremely low and extremely high temperatures.
- Resistance to permanent compression set. Silicone rubber will return to its original shape after being subjected to compressive forces.
- Availability in various durometers, colors, and specialty grades. Silicone rubber comes in numerous hardness levels, colors, and grades, so it can be used for many applications.
Common Applications of Silicone Rubber Gaskets
Some of the industries that commonly rely on silicone rubber gaskets include:
- Food Processing

While gaskets and O-rings serve a similar purpose of sealing out air or liquid, the two are designed for different situations and vary in appearance. Here, the team at Mercer Gasket & Shim will explain the differences between these sealing solutions to help you determine the best one for your application.
What Are Gaskets and O-Rings?
Gaskets are flat pieces of material used to make a seal between two flat surfaces, usually with a bolted joint. O-rings are round, ring-shaped pieces that must set in a groove to create a seal between two parts. While gaskets are most commonly circles, they are also manufactured in a variety of other shapes. Both gaskets and O-rings are made using flexible materials, but gaskets can also be made out of other rigid polymers and metals. The thickness of an O-ring can be customized to fit unique specifications, while gaskets may be layered with different coatings to work best for various applications.
Common Applications for Gaskets
- Electrical motors, power generators, and transformers
- Handheld communication devices
- Telecommunications equipment
- Aerospace and defense industry
- Transportation and automotive
- Medical devices
- Food and beverage industry
Common Applications for O-Rings
- Hydraulic seals
- Pipe joints
- Equipment with fluid seal points
- HVAC – Heating, Ventilation, and Air Conditioning
- Oil seals
- Fuel systems
- Food processing
- Pharmaceutical and medical industry
- Pulp and paper industry
Choosing the Best for Your Application
When deciding whether a gasket or O-ring is best for your application, consider the environment and function of the seal. When choosing the best seal, look for features such as shape, temperature, and pressure.
When a non-circular joint requires a good seal, an O-ring would be difficult to use because of its round shape. Gaskets can be customized to almost any shape, allowing them to work as a seal for a larger variety of applications.
The operating temperature of equipment will determine the best material to use for manufacturing the O-ring or gasket. While both can withstand a wide range of temperatures, gaskets are best for extreme temperature situations. However, O-rings perform better than gaskets in applications with extreme pressure.

Everything from the size of the gasket to its ability to withstand degradation and damage plays a role in how well it can stop the escape of air, gas, water, or other fluids. Gaskets are placed between two flush surfaces that have a channel for fluid movement. Because the two surfaces might not be perfectly flush or straight, they’re going to have gaps that fluid can move through. Gaskets correct those gaps by being compressed between the two surfaces to effectively eliminate any leakage pathway.
Key Gasket Selection Factors — Gasket Materials, Types, and Uses
Some factors that buyers should consider as they purchase gaskets include:
- The amount of force the two surfaces will exude on the gasket
- The degree of surface unevenness (which dictates how thick the gasket should be)
- The fluids and any ambient contaminants
- The compressibility of the gasket material
If you know all the details of the application environment, you can choose gasket materials that withstand exposure to water, acidic or alkaline chemicals, oxidation, and more factors as needed. You can also pick gaskets with the right thickness, longevity, and malleability.
Selecting the right characteristics prevents gasket failure. These parts can fail if they’re exposed to chemicals that degrade the material or if the forces acting on the gasket are too great. This guide will focus on the six most important tips for choosing the perfect gasket for your needs:
1. Selecting the Right Gasket Material
Metal gaskets work best in extremely high-pressure applications. They create an initial line contact or contain the fluid through wedging once the two flush connection surfaces touch. Metal gaskets are also known as ring gaskets, and have either an ovular or octagonal cross-section. Octagonal cross sections provide a great deal of strength in the face of high pressure, such as the BX type that can handle 20,000 psi. Metal gaskets are commonly used in oil and gas industrial systems and secured with high-tension bolting.
Popular materials for metallic gaskets include:
- Low carbon steel
- Stainless steel
Non-metallic, or soft, gaskets, compress between two surfaces with little tension or pressure. This makes them ideal for applications where the fluid contents have low pressure levels and can’t force a leak pathway through the gasket. Soft gaskets are affordable, easy to find in different materials and specifications, and able to be used in low-temperature applications.
One common non-metallic material option, graphite, can also be used in high-temperature applications up to 500°C. These gaskets come in full face varieties, which cover the entire face of a connecting surface, and inside bolt circle gaskets, which cover a smaller ring of surface area on the face; one common application for full face gaskets is temporarily connecting utility lines.
Popular materials for non-metal gaskets include:
- Compressed Non-Asbestos Fiber (CNAF)
- Polytetrafluoroethylene (PTFE)
. Semi-Metallic/Composite Gaskets
Composite gaskets use both metal and non-metal materials, giving them the ability to provide a reliable seal in a variety of environments with different pressure and temperature factors. They are commonly used in male-female, raised face, and tongue-and-groove flanges. Because they contain less metal, they are often more affordable.
Three popular types of composite gaskets are:
Other Material Types
- Elastomeric: Elastomers are polymers with similar stretch and flexibility to rubber. Elastomeric gaskets are commonly used in utility applications alongside non-metallic gaskets. While these gaskets are elastic and can be deformed, they’re incompressible and can’t reduce in volume.
- Fibrous: Fibrous gaskets are another specialized type of non-metallic gasket. This category includes materials such as aramid, carbon, and glass fibers, cork, mica, and more. Each material offers very distinct properties.
2. Evaluating Fluid Temperature, Corrosive Properties, and Pressure
When gaskets aren’t properly aligned to the application environment’s temperature, materials, or pressure, they are at an increased risk of failure. Each gasket’s material is best suited for a specific range of fluid or ambient temperature; silicone, for example, has a much wider temperature range (-30°F to 350°F) than neoprene, which is only viable at temperatures between 30°F and 180°F. One of the first considerations when choosing a gasket material is to know the minimum and maximum operating temperatures of the fluid.
The chemical makeup of the contained fluids should also determine which material your gasket has. Factors such as pH level, oil or water content, oxidation qualities, and more can corrode or destroy different materials through regular or irregular exposure.
Gaskets also perform differently depending on the pressure levels. Non-metallic gaskets, which can provide a compressed seal at relatively low pressures, cannot provide adequate resistance if the contained fluid is too pressurized; the fluid can force a path through the gasket’s seal. Synthetic rubbers, for example, often have a cap of 60 psi for reliable performance. Metallic gaskets, on the other hand, are well matched to the extremely high pressures in oil and gas processing plants.
3. Choosing the Best Types of Gaskets
Once you know which material is best for the end application, you can select the right type, or structure, of the gasket. Some popular varieties include:
- Jacketed Gaskets: These have a soft non-metallic interior and a metallic coating. Jacketed gaskets are available in many varieties, such as single- or double-jackets (which have a coating on one or both sides), corrugated jackets, and more. The metallic coating gives non-metallic gaskets better resistance to damage.
- Solid Gaskets: These solid metal gaskets are extremely durable, but they require a lot of compression force to create a seal.
- Spiral Wound Gaskets: This gasket style has windings of metallic materials in soft, non-metallic gaskets, which combines both resistance to damage and flexibility. Piping and pumping systems often use spiral wound gaskets because of the reliable seal.
- Kammprofile Gaskets: These have a metal core surrounded by non-metal material on the top and bottom. It can create a tight seal along the gasket’s edge with extra reinforcement. They’re also easier to repair than comparable composite gaskets.
4. Talking to a Gasket Design Engineer
Working with a gasket design engineer is an excellent choice for creating a custom gasket for unique applications or for expert assistance in selecting the features your system needs. If you choose the wrong materials, design style, and type, you may degrade the life span of the surrounding system. Further, mass manufacturing a flawed gasket type can result in a failed project or excessive expenses. Talk to a gasket design engineer about your design specifications and environmental factors that should shape the final product.
5. Testing for Gasket Performance
There are multiple factors to test on a new gasket design to ensure the materials, specifications, and style create an adequate and cost-effective seal. Regulatory or standardizing organizations like Underwriters Laboratories set objective standards that industrial and commercial parts must meet to be safe for sale or use. The same organizations often establish what sort of tests or testing conditions are necessary to certify that a product is safe. These tests assess a gasket’s ability to withstand temperature, chemicals, pressure, and compression to retain a seal.
6. Choosing the Right Gasket Manufacturer
The right manufacturer is essential for ensuring the material success of your project. Look for manufacturers that have experience creating gaskets for the industries or markets you serve. It’s also important to choose a manufacturer with established design, testing, and inspection capabilities, so the final product is high quality and reliable.

Cork is a highly resilient material used in manufacturing gaskets. It allows compression in one direction without dimension loss in the other. In addition, it is frequently combined with rubber granules that are excellent gasket components, especially for forming effective seals. They are resistant to corrosion and degradation by water, chlorides, and other environmental exposures.
Mercer Gasket & Shim offers full-face, square, and rectangular cork rubber gaskets in either a one-piece construction or dove-tailed fabrication for larger jobs. We also have an extensive inventory of products in our manufacturing facility, enabling a quick turnaround of parts for our clients.
What Is Cork Rubber?
Cork rubber — also referred to as rubber cork — has been at the forefront of gasket technology for over 50 years. This material is available in numerous sizes and variations and is utilized in various applications and industries. It is specially formulated with milled cork grain and synthetic rubber.
Typically, cork rubber combines first-grade granulated cork and a rubber polymer, such as natural rubber, synthetic rubber, silicone, nitrile, EPDM, or neoprene. Then, the components are held together with glycerin glue applied under specific heat and pressure conditions. This yields a composition (consisting of approximately 70% cork grain and 30% rubber) that is highly resilient and compressible, with minimal sideways flow.
Some additional benefits of combining rubber and cork in manufacturing gaskets include increasing the cork’s stability and enhancing the material’s shelf life. Rubber also tends to make cork denser, thereby eliminating additional leak-causing pathways. Lastly, properly selecting rubber granules can regulate the gasket’s expansion for optimal sealing.
Advantages of Cork Rubber
The combination of rubber and cork’s properties results in a highly resistant formulation best suited for volatile and rigorous environments. Cork rubber is also ideal for optimal sealing and chemical solutions for modern gasket applications thanks to the following advantages:
- Ability to absorb vibrations and shocks
- Ability to withstand fluid penetration (oil, solvent, and fuel) and sideways flow
- Acoustic insulation
- Versatility to be used with or without a pressure-sensitive adhesive (PSA) backing
- Excellent resistance to impacts
- High compressibility (cork) and flexibility (rubber)
- Moderate tolerance to fungus, acid, and extreme weather conditions
- Reduction of transmitted vibration levels
Applications and Industries of Cork Rubber Gaskets
Die-cut cork rubber sheets are readily available in an array of sizes, densities, and thicknesses for various industrial applications. Some of the most common ones are gaskets, spacers, bumpers, protective pads, stripping, electrical transformers, and switchgear.
Their versatility also enables them to meet the requirements and specifications of the following industries:

The location of a gasket is of utmost importance, especially if it is going to be exposed to the elements. For this reason it’s imperative to choose top quality weather resistant materials to enhance the longevity and performance of outdoor gaskets. There are a number of important factors to think about in regard to weather resistance including sunlight, temperature, ozone, and inclement weather conditions (rain, hail, sleet, snow, etc.).
Weather’s Effect on Gasket Performance
Many outdoor gaskets experience direct sunlight. This can increase internal temperatures to more than 140°F. In addition, heat cycling can accelerate compression set in many gasket materials.
On the opposite end of the spectrum, gaskets in many climates experience freezing temperatures during winter. Frozen gaskets are highly susceptible to cracking, and problems can intensify when the temperatures rise above freezing. As snow and ice melt, gaskets that stiffened due to cold temperatures are more apt to leak.
Additionally, gaskets often require ozone and ultraviolet light (UV) resistance. Ozone not only occurs in nature, but also can be generated by certain outdoor enclosures that house electrical components. UV exposure can also be detrimental to a gasket’s life and integrity.
UV and ozone resistant materials should always be considered for gaskets that will be outdoors or near electrical enclosures. Finally, whenever gaskets are compressed and then re-compressed by any type of weather conditions, it’s important to choose gaskets that have the ability to be rebound.
Materials That Stand Up to the Elements
The following are a few examples of commonly used materials that help minimize the impact of harsh weather conditions.
- Fluoroelastomer (Viton®) –This is a fluorocarbon-based synthetic rubber well-known for its excellent performance and resistance to chemicals. It is also highly resistant to many extreme environmental conditions. Fluoroelastomer can handle high temperatures, ozone, and oxygen, as well as fuels, mineral oil, and synthetic hydraulic fluids. It can operate in maximum temperatures from 400°F during continuous service and up to 500°F in intermittent service.
- Polyurethane – This compound features excellent abrasion resistance and tensile strength compared to other elastomers, and these qualities translate well into excellent performance in all weather conditions. It also features good resistance to ozone and operates in temperatures as low as -22°F and as high as 230°F.
- Ethylene Propylene Diene Monomer (EPDM) Rubber – EPDM rubber is compatible with a wide variety of materials and exhibits outstanding weather resistance. This synthetic rubber can resist the deteriorative effects of ozone, oxygen, heat, and weather, along with many chemicals, oils, and acids. EPDM has a wide range of serviceable temperatures, from -40°F to +250°F, and intermittent to +275°F. It also exhibits excellent resistance to steam and polar substances.
- Silicone – Silicone is an extremely versatile material. It features excellent elastomeric properties at both low and high temperatures. Silicone is highly resistant to oxygen, ozone, UV light, aging, weather, and extreme temperatures. It works in temperatures that range from -67°F to +400°F, and intermittent to +450°F.
There are numerous options for outdoor gasket sealing. The materials listed above have a number of advantages and disadvantages when it comes to cost and resistance to specific weather conditions.
