Product Description

Overview

This industrial spiral wound gasket is engineered for high-pressure, high-temperature sealing in critical flange connections. Designed to meet rigorous industry standards, it provides a reliable, long-lasting seal in demanding process environments. Its construction combines the strength of metal with the sealing properties of a non-metallic filler, creating a resilient gasket that accommodates flange rotation and surface irregularities. This specific configuration is tailored for DN500 PN16 piping systems, making it a vital component for maintaining system integrity and preventing leaks in large-diameter pipelines.
