ASME B16.20 Spiral Wound Gasket, 316L with PTFE, NPS 24" 600LB
Overview
This industrial-grade spiral wound gasket is manufactured to the exacting requirements of the ASME B16.20-2007 standard, ensuring reliable performance in high-pressure and high-temperature sealing applications. Designed for a nominal pipe size of 24 inches with a 600-pound pressure class rating, it features a robust construction with a 316L stainless steel outer ring and a winding of 316L metal combined with a polytetrafluoroethylene (PTFE) filler. This combination delivers a resilient, leak-tight seal capable of withstanding aggressive chemical service and variable operating conditions, making it a critical component for maintaining system integrity in demanding industrial environments.
Key Features
Engineered to ASME B16.20-2007 specifications for guaranteed dimensional accuracy and performance. Features a solid 316L stainless steel outer ring for precise centering on the flange and controlled compression. Spiral wound core combines 316L stainless steel for structural strength with PTFE filler for superior chemical resistance and sealing resilience. Suitable for a broad spectrum of corrosive media, including acids, alkalis, and solvents. Provides reliable sealing across a wide range of temperatures and pressures consistent with its 600LB rating. Designed for long-term, maintenance-free service in both indoor and outdoor industrial installations.
