5 Inch Aramid Gasket for Flat Face Flanges

The Value Brand GSNAG5 is a 5 inch ring gasket built from aramid fiber with a nitrile binder for industrial piping systems. It matches ANSI dimensions for 150 lb flat face flanges and ships with eight bolts for direct installation. The blue gasket handles temperatures from minus 100 to 700 degrees Fahrenheit and pressures up to 150 PSI.

Replacing Worn or Incompatible Flange Seals

Maintenance teams use this gasket when existing seals degrade from thermal cycling or chemical exposure in steam, oil, or water lines. The aramid construction resists creep better than plain rubber or compressed non-asbestos sheets under sustained bolt load. The jump is worth it when the service temperature exceeds the limits of standard elastomer gaskets or when flange rotation demands a firmer seating surface.

150 PSI Pressure Rating

The gasket comfortably handles saturated steam, hot oil, and chilled water services within the rated 150 PSI and 700 degree ceiling. It runs out of margin in applications above 150 PSI or where flange misalignment exceeds the 1/16 inch thickness compensation. The 5-3/16 inch inside diameter and 7-3/4 inch outside diameter fit the bolt circle precisely, leaving no extra sealing surface for oversized or damaged flange faces.

Questions about this item

What pipe size and flange standard does the 5-inch aramid gasket match?

The gasket is sized for a 5-inch pipe and fits ANSI 150 lb flat-face flanges.

How should the included bolts be torqued when installing this 1/16-inch thick aramid gasket?

Tighten the eight bolts in a star pattern to the flange specification; uneven torque on the thin aramid fibre material causes leaks.

When should this blue aramid gasket be replaced based on its temperature and pressure limits?

Replace it if the system exceeds 150 psi or 700 °F, or after any thermal cycle that takes the material below -100 °F.
