Inner Ring (also know as inner bolt circle) expanded PTFE gasket made from 100% multi-directionally expanded PTFE. Because it is dimensionally stable, it is ideal for many flange conditions. It has all of the benefits of conventional PTFE without the creep and cold flow that is commonly associated with this material.

Key features
* Chemically inert
* Dimensionally stable
* High tensile strength
* Resistant to creep & cold flow

Key benefits
* Versatile: use with all types of flanges & fluids
* Seals irregular flanges
* Retains stress, minimum re-torquing required
* Sealing reliability
* Long shelf life
* Easy to cut
* Light Clamping Force
