Frequently asked questions

Which filler should I choose for a spiral wound gasket?
Graphite is preferred for high temperature and steam service, PTFE for aggressive chemicals and high purity, and CAF for general-purpose applications. Our technical team helps match filler to your process medium, pressure, and temperature.
Do you supply spiral wound gaskets with inner and outer rings?
Yes. We manufacture spiral wound gaskets with inner rings, outer rings, or both, depending on flange type, pressure class, and sealing requirements.
What sizes and dimensions do you manufacture spiral wound gaskets in?
We manufacture spiral wound gasket dimensions from small instrument flanges up to large-diameter process flanges, covering ASME B16.20 standard sizes as well as custom dimensions built to your flange drawing.
What standards define spiral wound gasket specification?
Spiral wound gasket specification is primarily governed by ASME B16.20, which sets the dimensions, tolerances, and winding requirements for each flange size and pressure class. We manufacture strictly to this standard and supply an MTR confirming compliance.
