Overview
The 304 Stainless Steel Spiral Wound Gasket is a precision-engineered sealing solution designed for demanding industrial flange connections. It provides a reliable, leak-tight seal in high-pressure and high-temperature piping systems. This gasket is constructed with a spirally wound V-profile metal strip combined with a resilient filler, creating a robust seal that accommodates flange rotation and surface irregularities. Manufactured to the HG/T 20631 standard, it ensures consistent quality and dimensional accuracy for critical process applications.
