Description
1. Product Overview
Spiral Wound Gasket 304/Graphite — Sealing is a high-performance industrial sealing component engineered for demanding flange connections operating under high pressure and temperature conditions. Manufactured with SS304 stainless steel winding and flexible graphite filler, the gasket provides exceptional sealing integrity for critical process equipment. Its primary industrial use is in pipelines, pressure vessels, heat exchangers, and valve systems where reliable leak prevention is essential. The key value proposition lies in its ability to maintain tight seals across thermal cycling, pressure fluctuations, and aggressive chemical environments. Strategically, spiral wound gaskets are a preferred sealing solution across global heavy industries due to their durability, reliability, and compliance with stringent safety and operational standards.
