Also known as spiral-wound gaskets, these have a carbon steel outer ring and a 304 stainless steel inner sealing element with a graphite-based filler.

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.

Made of 110 copper, these gaskets handle steam applications up to 600° F. They are electrically conductive and resist water, Freon, and fuel oil.

In addition to withstanding temperatures up to 450° F, these silicone rubber gaskets resist water and salts.

These gaskets are made from a blend of graphite and Buna-N rubber to withstand temperatures up to 650° F.

Also known as Gore GR.

Often used with fiberglass flanges where you want to avoid overtightening, these gaskets seal under low torque. They’re made of soft, expanded PTFE that is also known as Gore UPG.

These pure PTFE gaskets have a slippery surface that prevents sticking.

In addition to oil, these blended aramid fiber/Buna-N rubber gaskets resist water and aliphatic hydrocarbons such as ethylene.
