Overview
The 321 Stainless Steel Spiral Wound Gasket is a precision-engineered sealing solution designed for demanding industrial flange connections. It is constructed to provide a reliable, leak-tight seal in high-pressure and high-temperature piping systems, including those with thermal cycling. This gasket combines the strength of a corrosion-resistant metal wind with the conformability of a resilient filler, making it a critical component for maintenance, repair, and operations (MRO) and original equipment manufacturing (OEM) applications.
Key Features
Engineered for high-pressure service up to 580 PSI Features a 321 stainless steel outer winding for excellent corrosion and heat resistance
Utilizes a flexible graphite filler for superior sealing performance across a wide temperature range
Spiral wound construction absorbs flange irregularities and compensates for thermal expansion
Suitable for both indoor and outdoor installation environments
Manufactured to meet recognized industry dimensional standards
