Overview
The 321 Stainless Steel Spiral Wound Gasket is a precision-engineered sealing solution designed for critical flange connections in industrial piping systems. Its spiral wound construction combines alternating layers of formed metal and soft filler material, creating a resilient seal that compensates for flange irregularities and thermal cycling. This specific configuration, built to established industry dimensional standards, ensures reliable performance in applications involving elevated temperatures and variable pressures.
Key Features
Constructed with a 321 stainless steel winding for excellent oxidation resistance and strength Features a high-purity graphite filler for superior thermal conductivity and stability The spiral wound design provides a spring-like action to maintain seal under fluctuating conditions
Engineered to seal effectively on standard raised face flanges Robust construction resorts to crushing and blow-out under pressure
