Spiral Wound Gaskets

Spiral Wound Gaskets - This type is made using metallic and filler material, usually carbon or stainless steel and are wound in a circular shape, rather than sheets. Spiral Wound Gaskets comprise a mix of metallic and filler material. Spiral wound gaskets have proven to be the most reliable sealing element.
Spiral Wound Gaskets are metal gaskets made with three key elements.
1) A metal spiral winding which is spot welded on the OD and ID.
2) A seal filler material to go between the winding layers. This material must be compatible with the application the spiral wound gasket is meant to seal.
3) An optional Outer guide ring (which is most common) an inner ring (for vacuum applications) or both for applications with pressure and vacuum.
