Spiratec lst spring would gaskets designed to give top sealing efficiency at limited bolt stress Pressure:<=200bar

SPIRATEC LST spiral wound gaskets designed to give top sealing as standard SPIRATEC spiral wound gasket,but uses thinner stainless steel spirals with additional graphite filler

LST gasket is duitable for limited bolt stress duties as recommended for certain materials in ASME code. Seals effectively at up to 200bar,well above the pressure normally associated with Class 150 and Class 300 flanges.
