Spiral wound gaskets are to he constructed as alternate plies of preformed metal windings (hoop) and plain fillers that are spirally wound when compressed between two flanges. Filler and strip (hoop) materia Ls 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.

For easier identification, we use a color coding system around the outside of the centering ring, permitting full identification of both the winding and filler materials.
Suitable for High temperatures and high pressures depending from selected materials.
