Overview
This 14-inch metal spiral wound gasket is engineered for reliable, high-integrity sealing in demanding industrial piping systems. Designed specifically for use with 150LB pressure class flanges, it provides a robust seal capable of withstanding significant mechanical stress and thermal cycling. The gasket's construction features a C-shaped winding pattern combined with an outer centering ring, ensuring precise installation alignment and enhanced resistance to crushing or blowout. It is manufactured to the stringent SH/T3407-2013 standard, guaranteeing dimensional consistency and performance reliability for critical process applications.
Key Features
C-shaped winding construction with an outer centering ring for stability Centering ring ensures perfect flange alignment and prevents over-compression Winding and filler combination provides a resilient, self-compensating seal
PTFE filler offers broad chemical resistance and low friction 304 stainless steel winding provides structural strength and corrosion resistance
Suitable for both indoor and outdoor service environments Conforms to industry-standard SH/T3407-2013 specifications
