Product Description

Overview

This 1-1/4 inch NPS spiral wound gasket is engineered for high-integrity sealing in demanding industrial piping systems. Manufactured in strict compliance with ASME B16.20-2007 standards, it is designed for flanges with a 900LB pressure class, providing a reliable seal in high-pressure applications. The gasket features a robust construction with a PTFE filler and 304 stainless steel winding, supported by inner and outer reinforcing rings for optimal seating and bolt load distribution. It is intended for indoor use where a durable, chemically resistant seal is paramount.

Key Features

Manufactured to ASME B16.20-2007 standards for guaranteed dimensional accuracy and performance. Rated for high-pressure applications up to 900LB flange class. PTFE (Polytetrafluoroethylene) filler provides exceptional resistance to a wide range of corrosive chemicals and solvents. 304 stainless steel inner and outer rings (C2230 configuration) offer structural stability and prevent gasket blow-out. 304 stainless steel winding provides resilience and recovery under varying pressures and temperatures. Non-paintable surface ensures material integrity is not compromised.
