ASA 1500 Spiral Wound Gasket – Carbon Steel Inner Ring

The ASA 1500 Spiral Wound Gasket with Carbon Steel Inner Ring is engineered for exactly the environments where failure is not an option, oil refineries, petrochemical plants, power generation facilities, and high-energy steam lines operating under extreme thermal and mechanical stress.
Rated to Class 1500, this gasket handles operating pressures up to approximately 255 bar (3,705 psi), making it a reliable sealing solution for ultra-high-pressure piping systems, pressure vessels, and industrial valves. Where soft-sheet gaskets would creep, degrade, or blow out, the ASA 1500 holds firm.

At the heart of this gasket's performance is its alternating construction—V-shaped metal plies interlocked with flexible graphite filler layers. This configuration functions like a precision-engineered spring, continuously adapting to thermal cycling, pressure surges, and vibration without losing sealing integrity. The result is a consistently tight seal across the full lifecycle of the installation.
