Spiral Wound No Inner Ring

Spiral Wound Gasket - No Inner Ring

The GFS Spiral Wound Gasket with No Inner Ring is engineered for ASME flanges with metal windings, filler material, and a centering ring. It offers excellent general-purpose performance for raised face flanges. Its durable construction and consistent compression deliver superior safety and exceptional sealing performance.

This gasket offers easy installation and removal, and seals pressures to flange ratings, in accordance with ASME B16.5. Suited to temperatures from cryogenic to 2000°F / 1093°C, depending on metal and filler, custom-tailored solutions accommodate a variety of conditions by combining various metals and filler materials.  Material offerings available for purchase are outlined below.

A centering ring accurately locates the gasket on the flange face, provides additional radial strength, and acts as a compression limiter. The spiral winding (sealing element) consists of preformed metal and soft filler material.

Optimizing gasket performance can be a very complicated process.  If you require the input or design assistance of a GFS engineer for your application, please contact GFS here.
