3 in Ring Flange Gasket

This ring flange gasket suits piping systems that require a 3 inch nominal pipe size and an ANSI Class 150 flange rating. The aramid fibre material with a Buna-N binder handles a wide temperature range from minus 100 degrees F up to 750 degrees F. It is intended for maintenance crews and plant engineers who need a reliable flat gasket for standard flanged connections.

Sustained temperature and pressure performance

The aramid construction resists creep and blow-out when the joint is held at elevated temperature for long periods. Rated for continuous service up to 750 degrees F, the gasket maintains its seal without the relaxation seen in softer sheet materials during extended thermal cycles. The 1/16 inch thickness provides the necessary compressibility to fill flange imperfections while retaining enough body to resist extrusion under steady internal pressure.

Aramid construction with supplied hardware

Blue colour coding allows quick visual identification in stores that use colour standards for material grade. The gasket ships with Grade A zinc plated carbon steel bolts so the joint can be assembled immediately without sourcing separate fasteners. The ring profile centres itself on the flange bolts, reducing the risk of misalignment during installation and making routine replacement faster for maintenance teams.

Questions about this item

How much heat can the 3-inch aramid ring gasket handle when it runs all day at the plant?

The gasket is rated for continuous service up to 750 degrees F and down to minus 100 degrees F, so it stays sealed through wide temperature swings.

What flange hardware must I already have to install this 3-inch ring gasket?

It fits ANSI Class 150 flanges with a 3 3/8 inch bore and 5 3/8 inch outside diameter, and the kit includes Grade A zinc-plated carbon steel bolts for mounting.

Will this blue aramid gasket seal properly against the older carbon-steel flanges we keep in service?

Yes, the Buna-N binder and aramid facing are compatible with standard carbon-steel flange faces used in Class 150 piping systems.
