Spiral Wound Gaskets With Outer Inner Ring

Additional Details

AIG Spiral Wound Gaskets with Inner and Outer Rings are engineered for use in critical applications where both mechanical and chemical resistance are essential. These gaskets are composed of a V-shaped metallic strip wound with a filler material (typically graphite), reinforced with an inner and outer ring made of carbon steel or stainless steel to provide optimal compression and centering.

The outer ring serves as a compression limiter and centering device, while the inner ring reinforces the gasket against inward buckling, especially in high-temperature and high-pressure environments. Ideal for fluctuating conditions involving heat, pressure, and corrosive media.

These gaskets conform to ASME B16.20 standards and are used across several demanding sectors.
