ASA 600 Spiral Wound Gasket – Carbon Steel Inner Ring
The ASA 600 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 600, this gasket handles operating pressures up to approximately 102.1 bar (1,480 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 600 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.
The Carbon Steel Inner Ring serves a critical structural function: acting as a compression stop that prevents over-tightening during installation and guards against blowout under extreme forces. Compatible with both raised-face and flat-face flanges, it delivers reliable performance across a wide range of industrial flange configurations.
