Spiral Wound Gaskets are manufactured through the spiral winding of a V-shaped metal strip and a strip of non-metallic filler material. The Spiral filler is actually what does the sealing, and the winding contains it from extrusion. This simple design has been modified to 4 common Spiral wound gasket styles.
Spiral Wound Gaskets of all shapes and sizes
2) Placing a metal ring on the inside dimension for the purpose of preventing the gasket from collapsing into the pipe line in Vacuum applications.
3) Gaskets made with inner and outer rings to contain both Vacuum and internal pressure applications.
4) low pressure applications and minimal vacuum pressure a winding and filler only gasket is sufficient.

Are there other metal gasket types?
Spiral wound gaskets are a type of mechanical seals used to prevent leaks in flanged joints in pipes, valves, and pressure vessels. They consist of a thin metallic strip and a soft filler material wound together in a spiral fashion, providing a tight seal under pressure. Spiral wound gaskets have been around for a long time, and are a proven safe technology. However, like any industry there are new products available that can do as good or even better in critical services. Kamm profile gaskets and RTJ (Ring type joint) gaskets are converting over long-time spiral wound customers.
