SPIRAL WOUND INNER RING GASKET

The Spiral Wound Gasket with Inner Ring is a premium-grade sealing solution designed to handle extreme pressure, temperature, and chemical conditions. The inner ring enhances gasket strength, prevents inward buckling, and protects the sealing element from media turbulence and erosion — making it ideal for critical flange joints in petrochemical, power generation, pharmaceutical, and oil & gas sectors.
