High-Temperature Metallic Pipe Gaskets
a Flat-Surface
Pipe Flange
Also known as spiral-wound gaskets, these have a 1/8” thick carbon steel outer ring and a 304 stainless steel sealing element with a graphite-based filler. The metal construction provides structural strength. These 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.
Gaskets for ANSI class flanges are sized so all gasket specifications meet ANSI standards. Gaskets for ANSI Class 600 flanges are compatible with high-pressure pipe flanges.

High-Temperature Chemical-Resistant Metallic Pipe Gaskets
a Flat-Surface
Pipe Flange
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 600 flanges are compatible with high-pressure pipe flanges.

Easy-Install High-Temperature Metallic Pipe Gaskets
Instead of bolt holes, these gaskets have tines that easily fit around flange bolts to ensure they’re properly aligned with pipe openings. The tine design also means you won’t have to retorque the flange for alignment, saving time. These gaskets are half as thick as our other metallic gaskets, so they're easier to slip in between flanges. Made from stainless steel, these gaskets add structural strength. They also withstand high temperatures, making them a good option for extreme environments. Because these don't have bolt holes, they work with multiple ANSI Class designations, so they're compatible with low-, medium-, and high-pressure pipe flanges.

High-Temperature Graphite Pipe Gaskets
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. Also known as ring gaskets, use them with raised-surface pipe flanges; they fit the surface inside the bolt holes and do not interfere with the bolt connection.
All gaskets are sized to meet ANSI standards. Gaskets for ANSI Class 600 flanges are compatible with high-pressure pipe flanges.

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 600 flanges are compatible with high-pressure pipe flanges.
