All standard o-ring sizes (imperial and metric) are available.
Custom o-rings are available in standard cross-sections (imperial and metric) to any length or ID. They will be molded or spliced using vulcanizing or adhesive depending upon application.

We can also supply encapsulated o-rings where one material is covered with a continuous layer of another material (usually Teflon^®).

All standard International sizes are held in stock for immediately delivery, however, Mercer is also able to supply speciality O-Rings at competitive prices. Encapsulated, PTFE, Viton^®, Kalrez Silicone and gas filled are just an example of typical non-standard materials we supply on a regular basis to a wide variety of valued customers.

Metallic O-Rings can also be manufactured to individual customer specifications.
Please contact us with your specific enquiries and let our Sales Team assist you in solving your sealing requirements.
