Durlon® 9000 Step Ring Gaskets

Gasket Resources Inc. has improved upon the original design of the “glued” Step Ring Gasket that has been the industry standard for years. The old design Step Ring Gasket consisted of a 1/16″ thick standard ring section plus a 1/16” thick inner ring section bonded together with an adhesive.

GRI is able to CNC machine Step Ring Gaskets out of a single piece of Durlon® 9000, all while maintaining the same dimensional design. The solid piece construction prevents the possibility of gasket separation and the unneeded maintenance cost of gasket material ending up in your process. Our easy to install Durlon” 9000 Step Ring Gaskets are great for low bolt load applications and raised face flanges that easily deflect.

Durlon® Sealing Products:

Safe, Reliable & Versatile

  • Widest possible range of service applications – number of different types of gaskets to be inventoried can be greatly reduced
  • Boost to process safety – limiting the number of gasket styles reduces the chance of installing the wrong gasket in the wrong service
