The LS_HT style gasket combines the corrosion and oxidation resistance of mica with the excellent sealability of flexible graphite. The mica, together with the metal spirals, acts as a protective barrier between the graphite and oxidizing process conditions or external air.

While Inconel 750 is commonly used for the winding metal, other alloys can also be selected to suit specific requirements. The LG_HT configuration is rated for service temperatures up to 800°C
We offer additional options for high-temperature gaskets.
The LS-HT-V Spiral Wound Gasket is a high-performance sealing solution engineered for extreme temperatures and aggressive media. It features a robust metal winding combined with a vermiculite filler, providing excellent sealing efficiency, outstanding oxidation resistance, and long-term durability.
This gasket is ideally suited for severe service conditions, including superheated steam, strong oxidizing environments, and other high-temperature applications.
With Loose Guide Ring (LS_LOR) utilizes a loose fit guide ring.
The LS_SS style gasket is specifically designed for highly corrosive environments. It features a spiral wound construction with a conventional outer guide ring and a serrated inner ring, providing a dual sealing design that fully engages the raised face from the OD to the bore.
This gasket is specifically designed for Hydrofluoric (HF) acid applications. It features a Monel and PTFE spiral winding, complemented by a carbon steel centering ring and a PTFE inner ring.
With widely usage, it is applicable to sealing under heavily alternating temperature or pressure such as the static sealing at flanges of pipeline, valves, pumps, heat exchangers, columns, manhole and hand hole. It has a wide application in petrochemical mechanical, electric power, metallurgical, ship-building, pharmaceu-tical, nuclear power and aerospace industries.
