6 Inch PTFE Flange Gaskets Full Face 1/8" Thick 150# Pressure Rating - 2 Pack for Plumbing, HVAC, and Industrial Pipe Connections

Made of PTFE, these gaskets have a slippery surface that prevents sticking. They are chemically inert (except to molten alkali metal and fluorine compounds). Full-face gaskets, these cover the entire face of flat-surface pipe flanges and align with the bolt holes. All gasket specifications are sized to meet ANSI standards. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges.
