PTFE Screen Gasket
A PTFE sealing ring retains a stainless steel screen across its central opening.
Product overview
Construction and mating components
The gasket sits between mating ferrule sealing faces and is compressed by the clamp joint. Select the seal profile, inside/outside diameters and material separately. Screen gaskets include a mesh element and are distinct from plain seals. The body specification lists DN20~100; the dimension chart has its own size rows. Read each range as marked rather than treating inch designations and DN values as interchangeable.
