Spiral Wound Gasket Manufacturer In Kichha

🔩 Spiral Wound Gasket – Detailed Overview

A Spiral Wound Gasket is a high-performance semi-metallic gasket designed for high pressure and high temperature applications. It is constructed by spirally winding a V-shaped metal strip (usually SS 304 / SS 316 / CS) with a soft filler material such as graphite or PTFE. This unique construction provides excellent resilience and sealing efficiency.
