Spiral Wound
Chesterton’s spiral-wound gaskets combine concentric layers of corrugated metal and soft filler (graphite or PTFE) for a high-performance flange sealing solution. Designed to withstand wide temperature and pressure ranges, they offer excellent recovery, reliability, and resilience against thermal cycling.
Ideal for demanding applications such as heat exchangers, vessels, and high-pressure pipe flanges in industries like petrochemical, power, and refining, these gaskets ensure leak-free operation and long-term flange integrity—even under extreme conditions.
