What Is a Spiral Wound Gasket?
A spiral wound gasket is a high-performance sealing solution designed to withstand extreme pressure and temperature. It’s manufactured by winding alternating layers of stainless steel (SS304, SS316) and filler materials such as graphite or PTFE. Spiral Wound Gasket Manufacturers play a vital role in industries requiring leak-proof, durable, and high-performance sealing solutions. At Unifit Metalloys, we specialize in manufacturing Spiral Wound Gaskets in SS304, SS316, and exotic alloys to meet global standards.
Thanks to their strength, resilience, and durability, spiral wound gaskets are widely used in heat exchangers, boilers, condensers, pressure vessels, and pipelines across oil & gas, petrochemical, and power generation industries. Leading Spiral Wound Gasket Manufacturers provide gaskets suitable for a wide range of industries, ensuring consistent sealing for critical operations.
