SPIRAL WOUND GASKETS

For applications with high temperature variations (thermal cycling), pressure variations, or flange rotation problems, gaskets with adequate flexibility and recovery are required. Spiral wound gaskets are designed to meet these demanding conditions.

Our Spiral wound gaskets are made of a preformed metallic strip and a soft filler material (PTFE, or Flexible Graphite), wound together under pressure. The metal strip, in 304, or 316 Stainless Steel, holds the filler resulting in excellent mechanical resistance, resilience, and recovery. An inner and/or outer retaining ring option is available in 304 Stainless Steel or Carbon Steel.

Sizes

These gaskets are available in standard ANSI pipe flange dimensions from 1/2” and pressures from 150 psi to 2500 PSI. If you have special requirements, please use or RFQ page or call us. We can help!
