High-Temperature Metallic Gasket

Manufacturer part: 44955K465

These gaskets have a 1/8" thick carbon steel outer ring and a 304 stainless steel inside sealing element with a PTFE filler. The PTFE is chemically inert (except to molten alkali metal and fluorine compounds). The metal construction provides structural strength. These gaskets, also known as spiral-wound gaskets, can be used with both flat-surface and raised-surfaces pipe flanges; they fit the surface inside the bolt holes and do not interfere with the bolt connection.All gasket specifications are sized to meet ANSI standards.Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges.
