Overview
This ASME B16.20-compliant spiral wound gasket is engineered for demanding 300LB class piping connections. It is constructed with a precision-wound C2230 configuration, combining the strength of metal with the chemical resistance of a PTFE filler. The inclusion of a 304 stainless steel outer ring ensures proper alignment during installation, preventing gasket blow-out and simplifying bolt-up on flanged joints. Designed for reliability in critical service, this gasket provides a resilient, long-lasting seal in process, power, and industrial fluid handling systems.
Key Features
Manufactured to ASME B16.20-2007 standards for dimensional consistency and performance C2230 winding configuration with a 304 stainless steel outer centering ring Filler material of pure PTFE (Polytetrafluoroethylene) for broad chemical compatibility
Suitable for both indoor and outdoor applications in varied environmental conditions Non-paintable, ready-to-use construction requiring no additional sealants Provides a reliable seal for 300LB pressure class flanged connections
