Product Details
What Are Spiral Wound Gaskets?
A Spiral Wound Gasket (SWG) is a type of gasket made from alternating layers of metal strips and non-metallic filler materials, wound in a spiral formation. This construction creates a flexible, yet durable, sealing element that can accommodate a wide range of temperature and pressure conditions.
The metal winding imparts strength and resilience, while the filler material—often made of graphite, PTFE, or other sealing materials—enhances the gasket’s ability to seal effectively, even in harsh, chemically aggressive environments.
Spiral Wound Gaskets are widely used in industries where tight seals are required to maintain system integrity, prevent leakage, and ensure operational safety. They are well-suited for high-pressure, high-temperature applications and environments prone to vibration and thermal expansion.
