Spiral wound gaskets — made with an alternating combination of formedmetal wire and soft fillermaterials — form avery effective seal when compressed between two flanges.A V-shaped crown centered in the metal strip acts as a spring, giving the gaskets greater resiliency under varying conditions. Filler and wire material can be changed to accommodate different chemical compatibility requirements. If the load available to compress a gasket is limited, gasket construction and dimensions can be altered to provide an effective seal.

A spiral wound gasket may include a centering ring, an inner ring or both. The outer centering ring accurately positions the gasket within the flange and acts as a compression limiter, while the inner ring provides additional radial strength. The inner ring also reducesflange erosion and protects the sealing element.

Resiliency and strength make spiral woundgaskets an ideal choice under a variety of conditions and applications. Widely used throughout refineries and chemical processing plants, spiral wound gaskets are also effective for power generation, aerospace, and a variety of valve and specialty applications.

The ASME B16.20 gasket specification has been updated and changed to a new recommended standard. The new criteria incorporates a default to inner rings in all graphite-filled spiral wound gaskets unless the purchaser specifies otherwise. However, a graphite-filled spiral wound gasketwithout an inner ring will still be stamped with and in compliance to the ASME B16.20 standard.

Style RW

General purpose gasket suitable for flat face and raised face flanges up to Class 2500

Centering ring accurately locates the gasket on the flange face, provides additional radial strength, and acts as a compression limiter

Spiral winding (sealing element) consists of pre-formed metal and soft filler material

NOTE: An inner ring is recommended for applications above Class 600, due to the high available bolt load. See Style RWI.

Style RWI

Suitable for flat face and raised face flanges up to Class 2500

Recommended for higher pressure applications, for use with PTFE fillers, and when delineated by ASME B16.20

Inner ring acts as a compression limiter and protects sealing elements from process media attack

Style R

Suitable for tongue and groove, male-female, or groove-to-flat face flanges

Spiral winding only, containing preformed metal and soft filler material

Inner and outer diameters of winding are reinforced with several plies of metal without filler to give greater stability

NOTE: Also available with inner rings Style RI.

MC and MCR Gaskets

For Manhole Cover Assemblies
