Overview
The 304 Stainless Steel PTFE Spiral Wound Gasket is a precision sealing component designed for high-integrity flange connections in demanding process environments. Engineered to withstand aggressive media and high mechanical loads, this gasket provides a reliable, leak-tight seal in piping systems, pressure vessels, and pump assemblies. Its spiral wound construction combines the strength of metal with the sealing properties of a soft filler, creating a resilient seal that accommodates flange surface irregularities and thermal cycling.
Key Features
Robust spiral wound construction with 304 stainless steel windings PTFE (polytetrafluoroethylene) filler for exceptional chemical resistance Integrated inner and outer carbon steel retaining rings Retaining rings ensure precise gasket centering during installation Rings prevent over-compression and gasket blow-out Designed to seal effectively under high bolt loads Conforms to standard dimensional specifications for interchangeability
Specifications
Material Construction: 304 Stainless Steel Windings with PTFE Filler Retaining Ring Material: Carbon Steel Nominal Pipe Size: 1.5 inches (DN40) Pressure Class: 580 PSI (PN40) Bore Diameter: 1.77 inches Gasket Style: Type B with Inner and Outer Rings Pack Quantity: 50
Applications
Sealing chemical and hydrocarbon processing flanges High-pressure steam and utility piping systems Refinery and petrochemical plant pipework Power generation and boiler feed systems Industrial pump and compressor connections Any application requiring a resilient, chemical-resistant seal for raised face flanges
