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.
Type CGI (Gasket with Centering Ring & Inner Ring)
- Solid metallic inner & outer ring
- Suitable for high pressure and temperature applications
- Standard spiral wound gasket for raised face applications
- Effectively reduces fluid turbulence and flange erosion, protecting the sealing surface.
- Minimizes gasket damage by shielding the bore and inner windings from wear and tear.
- Wide choice of materials for filler and metal strip
- Versatile sealing solution for both standard operations and highly critical industrial environments.
Type CG (Gasket with Centering Ring)
- Solid metallic outer ring used as a centering device and compression stop
- Used mainly on raised face and flat face flanges
- Wide choice of materials for filler and metal strip
- Type CG gasket has a centering ring for alignment and prevents shifting.
- Suitable for medium pressures and temperatures in automotive, HVAC, and plumbing.
Type GI (Gasket with Inner Ring)
- Solid metallic inner ring
- High pressure & high temperature capability
- Male to female flanges in vessels, valves and pumps
- Wide choice of materials for filler and metal strip
- General and critical duties
- The inner ring provides support and reinforcement in high-pressure/corrosive environments
- These gaskets are ideal for harsh industrial applications involving chemicals and solvents.
Type G (Gasket only)
- Wide choice of materials for filler and metallic strip
- Suitable for high pressure and temperature applications
- Recommended flanges are tongue & groove, male to female and flat face to recess in vessels, valves and pumps
- These are versatile and ideal for non-extreme pressure/temperature joints.
- Type G Gasket commonly used in the automotive, plumbing, and general industries.
