Ultra-Chemical-Resistant Compressible
Reinforced PTFE Pipe Gaskets with Bolt Holes
Reinforced with a stainless steel insert, these soft expanded PTFE gaskets are stronger and can hold their shape better than gaskets without an insert. They’re chemically inert (except to molten alkali metal and fluorine compounds). Commonly called full-face gaskets, they cover the entire face of flat-surface pipe flanges and align with the bolt holes. Gaskets are compatible with low-pressure pipe flanges; all gasket specifications are sized to meet ANSI standards.

High-Temperature Graphite Pipe Gaskets with Bolt Holes
Able to withstand temperatures up to 750° F, these graphite gaskets have a stainless steel insert for strength to handle pressure up to 1,000 psi. Commonly called full-face gaskets, they cover the entire face of flat-surface pipe flanges and align with the bolt holes.
All gaskets are sized to meet ANSI standards. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges. Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges. Gaskets for ANSI Class 600 flanges are compatible with high-pressure pipe flanges.

Ultra-High-Temperature Vermiculite Pipe Gaskets with Bolt Holes
Our highest temperature gaskets, these are made of vermiculite to withstand temperatures up to 1800° F. They are reinforced with a stainless steel insert for added strength under pressures up to 2,900 psi. Commonly called full-face gaskets, they cover the entire face of flat-surface pipe flanges and align with the bolt holes. Gaskets are compatible with low-pressure pipe flanges; all gasket specifications are sized to meet ANSI standards.
