Product Line

Key Products

Ring Type Joint Gaskets (RTJ)

RTJ gaskets are metallic rings for high-pressure, high-temperature flanges, used in oil, petrochemical, valves, and pipelines, compliant with ASME B16.20 and API 6A.

Spiral Wound Gaskets (SWG/SPW)

Spiral Wound Gaskets seal up to 250 bar and -200°C to 1000°C. Easy to install and remove without flange damage, with materials adaptable to varied conditions.

Insulating Gasket Kit – Type F

Installed within the bolt circle, the outside diameter extends to the inside of the bolt hole circle. Bolts assist with accurate alignment during installation.

Flat Cut Gaskets

CNAF, PTFE, and Graphite flat cut gaskets provide reliable sealing, combining chemical resistance, durability, and high-temperature performance.
