Value Brand 8 in Ring Gasket 1/16 in Aramid Blue

8-inch Aramid Ring Gasket for ANSI 150 Flanges

This 8-inch ring gasket uses aramid fibre with a Buna-N binder to seal ANSI Class 150 flange connections. The blue material measures 1/16 inch thick with an 8-1/2 inch inside diameter and 11 inch outside diameter. It suits maintenance crews and plant engineers who need a non-metallic, non-detectable gasket for standard piping systems.

Temperature range and sustained sealing behaviour

The gasket operates continuously from minus 100 degrees F up to 750 degrees F, so it remains stable through wide thermal cycles in steam, oil or water service. Aramid fibre resists creep better than many organic sheets, helping the joint maintain bolt load over long periods without retorquing. The Buna-N binder adds resistance to hydrocarbon fluids while the material stays non-metal-detectable for process lines that require it.

Installation notes and common pitfalls

Grade A zinc-plated carbon steel bolts are included, so the hardware matches the gasket in one pack. Centre the 8-1/2 inch bore on the flange face before tightening in a star pattern to avoid pinching the thin 1/16 inch material. Over-torquing is the usual cause of splits or extrusion, especially near the 750 degree F upper limit where the binder softens. Verify flange finish and parallelism first; rough or warped faces will leak regardless of gasket quality.
