High-Temperature Silicone Rubber Pipe Gaskets
 |
In addition to withstanding temperatures up to 450° F, these silicone rubber gaskets resist water and salts. 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. Gaskets are compatible with low-pressure pipe flanges; all gasket specifications are sized to meet ANSI standards.

High-Temperature Silicone Rubber Pipe Gaskets with Bolt Holes
 |
Resistant to water and salts, these silicone rubber gaskets can handle temperatures up to 450° F. 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.
