Overview
The C-Gasket with Outer Ring is a precision-engineered metallic wound gasket designed to create a robust, leak-tight seal in high-pressure, high-temperature flanged connections. This specific 5-inch model is manufactured in strict accordance with the HG/T 20631-2009 standard, ensuring dimensional consistency and performance reliability for industrial piping systems. Its core construction utilizes a resilient 304 stainless steel winding with a PTFE (polytetrafluoroethylene) filler, delivering both mechanical strength and excellent chemical resistance. The inclusion of a solid 304 stainless steel outer ring provides critical benefits for installation and performance, making this gasket a superior choice for demanding service conditions.
Key Features
Engineered to meet HG/T 20631-2009 standard specifications for guaranteed compatibility Constructed with a durable 304 stainless steel winding for structural integrity and corrosion resistance Features a PTFE filler layer for effective sealing and broad chemical compatibility Incorporates a solid 304 stainless steel outer ring for improved gasket alignment and containment Designed to withstand high-pressure applications rated for 900 lbs The outer ring helps prevent over-compression and blow-out of the winding under pressure fluctuations Provides reliable performance across a wide range of thermal cycling conditions Suitable for use in standardized ANSI flanged piping assemblies
