  • Full-face design seals entire flange surface

  • Eight zinc-plated Grade A bolts included
  • 1/8 in thickness provides reliable compression seal

Full-Face Flange Gasket 4 in

This full-face flange gasket seals 4-inch ANSI Class 150 flanged connections in industrial piping systems. The SBR rubber construction resists water and mild chemicals across a broad temperature range. Supplied with eight Grade A zinc-plated carbon steel bolts for immediate installation.

Sustained sealing to 180 degrees F

The gasket maintains its seal continuously at temperatures up to 180 degrees F without hardening or extruding. At the low end it stays flexible down to -20 degrees F, preventing leaks during cold starts. Eight bolt holes distribute clamping force evenly around the 9-inch outside diameter.

1/8-inch SBR thickness decides fit

The 1/8-inch thickness determines whether the gasket fills your specific flange gap and compresses correctly under the available bolt load. Verify that this dimension matches the flange design before ordering; no other thickness is included.

Questions about this item

How hot can the SBR material get before it degrades during continuous service?

The gasket is rated for a maximum operating temperature of 180 degrees F, so it remains stable during all-day use within that limit.

Which mating flanges and bolt pattern does this 4-inch full-face gasket require?

It matches ANSI Class 150 flanges with an 8-hole pattern and 3/4-inch bolt holes, and the kit includes eight Grade A zinc-plated carbon steel bolts.

Will the included zinc-plated bolts hold up against older steel flanges that may have surface corrosion?

The Grade A zinc-plated carbon steel bolts provide corrosion resistance suitable for mating with existing steel flanges in typical industrial plumbing installations.
