Spiral Wound Gasket, 304 Steel & Graphite, DN200 600LB, Pkg Qty 2
Overview
This industrial-grade spiral wound gasket is engineered for critical sealing applications in high-pressure and high-temperature piping systems. Designed to meet rigorous HG standards, it provides a reliable, leak-tight seal for flange connections in demanding process environments. The gasket features a robust C-shaped construction with an integral outer centering ring, which ensures precise alignment during installation and prevents over-compression of the sealing element. Its combination of 304 stainless steel windings and a flexible graphite filler delivers exceptional performance across an extreme thermal range, from cryogenic conditions up to 1,500°F.
Key Features
C-shaped construction with outer centering ring for easy alignment and installation. High-temperature graphite filler rated for continuous service up to 1,500°F. 304 stainless steel windings provide excellent corrosion resistance and mechanical strength. Suitable for both indoor and outdoor industrial applications. Manufactured to HG/T 20631-2009 standards for consistent quality and dimensional accuracy. Designed for Class 600LB pressure rating in nominal pipe size DN200 (approximately 8 inches).
