  Flange Metal Spiral Wound Gasket   

 

The gasket may include a centering ring, an inner ring or both. The outer centering ring enters the gasket within the flange and acts as a compression limiter, while the inner ring provides additional radial strength. The inner ring also reduces flange erosion and protects the sealing element. Resilience and strength make spiral wound gaskets an ideal choice under a variety of conditions and applications. Widely used in refineries and chemical processing plants, power generation, aerospace, and a variety of valve and special applications. As environmental regulations and industry requirements become increasingly stringent, new and custom applications are continuing to evolve. Wherever you need a strong, resilient seal, our spiral wound gaskets provide an effective solution.
