Spiral Wound Gaskets

Spiral Wound Gaskets

Spiral wound gaskets provide superior performance and consistent compressibility. This process of precise winding density control provides a gasket designed to meet your specified seating stress and assures consistent sealing of your most critical fluids. Spiral Wound Gaskets are durable and easily installed and removed. Spiral Wound Gaskets seal pressures to flange ratings, in accordance with ASME B16.20. These gaskets accommodate a variety of conditions by combining various metals and filler materials. They are ideal for hydrocarbon processing and refining, petrochemical processing, chemical processing, power generation, pulp & paper and oil and gas industries.


High Operating Pressures and Temperatures

Spiral-wound gaskets comprise a mix of metallic and filler material. Generally, the gasket has a metal (normally carbon rich or stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flexible graphite) wound in the same manner but starting from the opposing side. This results in alternating layers of filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support.

Spiral Wound Gaskets are offered in many profiles and materials.  If you require the input or design assistance of a GFS engineer for your application, please contact GFS here.

Spiral Wound Gaskets with no Inner Ring (RW) is engineered for ASME flanges with metal windings, filler material, and a centering ring. This style offers excellent general purpose performance for raised face flanges. 

Spiral Wound with Inner Ring (RWI) features an inner ring, spiral winding, filler material, and a centering ring for use in higher pressure applications.
