Overview
This spiral wound gasket is engineered for high-pressure sealing in critical industrial piping and flange systems. It is constructed to provide a reliable, leak-tight seal in demanding applications involving elevated pressures, thermal cycling, and aggressive media. The design incorporates inner and outer carbon steel retaining rings, which ensure precise placement during installation, prevent over-compression of the sealing element, and add structural stability. Conforming to the international GB/T4622.2-2003 standard, this gasket delivers consistent, predictable performance for maintenance and OEM applications.
Key Features
Engineered for high-pressure service up to 363 PSI (PN25) Construction features 304 stainless steel windings for strength and resilience PTFE (polytetrafluoroethylene) filler provides superior chemical resistance Inner and outer carbon steel retaining rings for precise positioning and compression control Retaining rings prevent gasket blow-out and seal failure under pressure cycling Conforms to the dimensional and material specifications of GB/T4622.2-2003
