Overview
This 10-inch, 600LB class metal spiral wound gasket is engineered for demanding industrial sealing applications where reliability is critical. It is constructed with a precision-wound spiral of 316L stainless steel, filled with a layer of PTFE (polytetrafluoroethylene). This combination delivers a robust seal capable of withstanding high mechanical loads and aggressive media. The inclusion of an outer containment ring, or centering ring, ensures proper alignment during installation, prevents over-compression of the sealing element, and protects the windings from damage. Manufactured in compliance with the HG/T 20631-2009 standard, this gasket is a trusted component for maintaining leak-free integrity in high-pressure, high-temperature flanged systems.
Key Features
Engineered with a 316L stainless steel winding for superior corrosion resistance PTFE filler provides exceptional chemical inertness and a low-friction sealing surface Outer containment ring guarantees correct gasket placement and prevents over-tightening Rated for continuous service in temperatures up to 500°F Suitable for a wide range of pressures within the 600LB class rating Constructed to the exacting dimensions of industry standard HG/T 20631-2009
