Product Description

 

PTFE GASKETS come in all shapes and sizes,Gaskets are an integral component of any device which requires the confinement of a gas or liquid. They compensate for the unconformity of mating surfaces. These surface irregularities may be minute or large depending on the purpose of the device but in all cases, the gasket is required to compensate for the difference while limiting the flow of fluid in either direction. Gaskets differ from seals in that gaskets are normally cut from sheets or rolls while seals are formed individually in their own configuration. A flat cut gasket is derived from material of specific thickness and to a configuration that is designed for a specific application
Expanded PTFE - EPTFE Gasket material is a soft and conformable material that is ideal for applications with limited bolt load torque available. Or in applications such as glass lined pipe where excessive bolt load will cause more problems than it will solve. If you have never touched this exceptional sealing material think of a dense marshmallow. It has the same chemical resistance and temperature range as any PTFE but it is soft and will effect a seal much quicker than regular PTFE gasket material
