Spiral Wound Gasket Low Stress

The Spiral Wound Gasket Low Stress LSSW is designed to seal at lower stress than the conventional gasket. The required Y factor is in the range 5.000 ÷ 7.500 psi against 10.000 psi required by the standard gaskets ASME B16.20. The spiral wound gaskets LSSW are designed for the classes 150 and 300 lbs and are available equipped with all filler, winding and ring materials. The inner ring is always suggested to enhance the sealing efficiency.
