Overview
This D-Ring style spiral wound gasket is engineered for high-integrity sealing in flanged connections subjected to extreme pressure and temperature. Designed with a nominal pipe size of 3.1 inches and a 900-pound pressure class rating, it is built for critical service in chemical processing, power generation, and oil and gas applications. The gasket's robust metal-wound construction ensures a reliable, leak-free seal that accommodates thermal expansion and system vibration, maintaining performance under cyclical loads.
