Overview
This spiral wound gasket is engineered for high-pressure sealing in demanding industrial piping and vessel applications. It is constructed to provide a reliable, leak-tight seal in flange connections subject to thermal cycling, pressure fluctuations, and challenging media. The design incorporates both internal and external centering rings for secure installation and optimal performance. Manufactured in compliance with the SH/T3407-2013 standard, this gasket delivers consistent quality and interoperability in critical service environments.
Key Features
Robust 304 stainless steel winding for strength and corrosion resistance
