Tsinseal® Sealing gasket is special designed for flange sealing and insulating in all critical services. It is suitable for raised face, flat face and ring type joint flanges in all pressure classes ANSI150~2500# and API 2~10K psi service. The Tsinseal® Sealing gasket has been use in all over the world because of the superior sealing characteristics and excellent dielectric properties.

Advantages and Benefits
The gasket material incorporates high strength, glass reinforced epoxy laminated bonded to a stainless steel core. This provides the strength of a traditional metallic gasket while maintaining complete electrical insulation between the flange faces. Seal grooves are machined through the laminate insulating material and into the stainless steel core which provides a strong base for the seal to seat into and breaks the potential leak path that is inherent in glass laminate materials. Spring-energized PTFE internal face seals are installed in the dovetail shape seal grooves to provide the reliable sealing.
