Zoro Select Graphite Flange Gasket

The Zoro Select BULK-FG-968 is a full-face gasket built for 4 inch pipe flanges rated to ANSI Class 150. It suits maintenance crews and plant engineers who need a reliable seal on piping systems handling extreme temperatures. The graphite facing with 316 stainless steel insert handles services from minus 400 degrees F up to 975 degrees F. Gray color and metal-detectable construction are not featured on this model.

Check flange specs before ordering

Verify that the mating flanges are full-face pattern with eight bolt holes matching a 3/4 inch diameter. Confirm the flange outside diameter measures 9 inches and the inside diameter is 4 1/2 inches so the gasket seats correctly. Ensure the service temperature stays within the minus 400 to 975 degree F range. No fasteners are included, so have the correct bolts and nuts ready for assembly.

Fits 4 inch Class 150 piping systems

This gasket sits between two full-face flanges and requires no separate binder material. The 1/16 inch thickness compresses to fill minor surface imperfections while the stainless insert resists blow-out under pressure. It frees the joint from spiral-wound or ring-type alternatives that need different groove profiles. The graphite facing conforms to flange faces without additional sealants in most standard installations.
