Overview
This industrial-grade spiral wound gasket is engineered for high-integrity sealing in demanding, high-pressure piping systems, particularly in outdoor environments. It is designed to create a reliable, leak-tight seal between flanges, capable of withstanding significant pressure and thermal cycling. The gasket's construction utilizes a precision-wound spiral of alternating metal and filler materials, providing both mechanical strength and sealing resilience. Its 4-inch nominal pipe size (DN100) and pressure class rating make it suitable for a wide array of critical industrial applications where sealing performance is non-negotiable.
Key Features
Robust construction with alternating layers of 304 and 316L stainless steel windings High-density flexible graphite filler for superior conformability and seal Internal and external carbon steel centering rings for precise alignment Centering rings prevent gasket blow-out and protect the winding from over-compression Rated for PN40 pressure class, suitable for operating pressures up to approximately 580 PSI Engineered for reliable performance in outdoor applications, resisting environmental exposure Conforms to common international dimensional and material standards for flange connections
