Overview

This industrial-grade spiral wound gasket is engineered for high-integrity sealing in demanding, high-pressure piping systems, particularly in outdoor environments. It is designed to create a reliable, leak-tight seal between flanges, capable of withstanding significant pressure and thermal cycling. The gasket's construction utilizes a precision-wound spiral of alternating metal and filler materials, providing both mechanical strength and sealing resilience. Its 4-inch nominal pipe size (DN100) and pressure class rating make it suitable for a wide array of critical industrial applications where sealing performance is non-negotiable.

Key Features

Robust construction with alternating layers of 304 and 316L stainless steel windings High-density flexible graphite filler for superior conformability and seal Internal and external carbon steel centering rings for precise alignment Centering rings prevent gasket blow-out and protect the winding from over-compression Rated for PN40 pressure class, suitable for operating pressures up to approximately 580 PSI Engineered for reliable performance in outdoor applications, resisting environmental exposure Conforms to common international dimensional and material standards for flange connections

Frequently Asked Questions

What are the exact specifications and pressure rating of this spiral wound gasket?
This is a 4-inch (DN100) gasket with a pressure class rating of PN40 (approximately 580 PSI). It is constructed with alternating layers of 304 stainless steel and 316L stainless steel, filled with a flexible graphite sealing element, and includes both inner and outer containment rings for stability.
What are the typical applications or use cases for this specific gasket configuration?
This gasket is designed for outdoor flange connections in demanding industrial piping and pressure vessel systems. Its 304/316L steel and graphite construction makes it suitable for a wide range of services, including steam, hydrocarbons, and many chemical processes, where a resilient, high-pressure seal is required.
How is this product packaged, and what is the minimum order quantity?
The gaskets are packaged 10 per box. The minimum order quantity is one package (10 gaskets). Each gasket is individually protected to prevent damage to the wound sealing layers during shipping and handling.
