Overview
The 304 Stainless Steel D-Ring Spiral Wound Gasket is a precision-engineered sealing solution designed for high-pressure, high-temperature flange connections in industrial piping systems. Its robust construction provides a reliable metal-to-metal seal, preventing leakage of aggressive fluids, steam, and gases in demanding process environments. This gasket is manufactured to the international GB/T4622.2-2003 standard, ensuring dimensional accuracy and compatibility with standard flange faces.
Key Features
Engineered for high-pressure service up to approximately 914 PSI. Constructed with a resilient spiral wound design for superior sealing performance. D-Ring (outer metal ring) construction provides radial stability and prevents over-compression. Flexible graphite filler offers excellent thermal conductivity and chemical resistance. 304 stainless steel windings provide strength, corrosion resistance, and spring-like recovery. Designed for dimensional interchangeability with standard flange specifications.
