Ultra-Chemical-Resistant Food and Beverage Compressible PTFE Gasket Material

Made of FDA-listed material for use with food and beverage, these expanded PTFE sheets are compressible to ensure a tight seal. They are chemically inert (except to molten alkali metal and elemental fluorine). Cut with a utility knife or gasket cutter.

Ultra-Chemical-Resistant Compressible PTFE Gasket Material

More compressible than pure PTFE, these expanded PTFE gasket sheets and discs ensure a tight seal. They are chemically inert (except to molten alkali metal and elemental fluorine). Cut with a utility knife or gasket cutter.

Ultra-Chemical-Resistant ePTFE Made-to-Order Gaskets

Let us precision cut a gasket for you to your exact specifications using your DXF file. These gaskets are made of soft expanded PTFE, which is chemically inert (except to molten alkali metal and elemental fluorine).

First select a thickness, then select a sheet size that’s large enough to accommodate your gasket. Gasket cross section and bolt hole diameter must be at least 0.093". Finally, send us your DXF file. Depending on the size of your gasket, we’ll send you as many same-design gaskets as a sheet will yield, up to 20 gaskets for 12"×12" sheets, and up to 40 gaskets for 24"×24" sheets.
