Gaskets

Joint sheets are sheet-shaped gasket materials that consist of a fibrous material, a filler, and rubber, offering high flexibility. Machined to the required shapes and dimensions, they are used for piping and equipment.

Spiral wound gaskets are a semi-metallic gasket consisting of a V-shaped thin metallic band plate and a non-metallic cushioning material. Capable of being used even under high temperatures and pressures and offering outstanding sealing performance, the gaskets are used in piping and equipment in a wide range of fields including oil refining, petrochemicals, power generation, and LNG terminals.

Our Metal gaskets have been developed for high-temperature/pressure applications where soft gaskets cannot be used or for applications requiring extreme sealing performance. Gaskets made from mild steel, pure iron, stainless steel, copper, aluminum, titanium, special alloys, etc. can be selected to suit the individual application.

Expanded graphite (GRASEAL™) is produced by subjecting natural high-purity graphite crystal to chemical and heat treatments. It offers outstanding heat resistance, chemical resistance, and flexibility with little creep.

Available in sheet and cut gasket. For specific sizes please refer to the brochure.

PTFE-based gaskets are used in various industries including fine chemicals, petrochemicals, pharmaceuticals, food, and semiconductors for their outstanding chemical resistance and anti-staining property.

Available in sheet and cut gasket. For specific sizes please refer to the brochure.

The gasket has a rubber compound applied to its woven fabric, and is suitable for large-diameter or distorted flanges or where a high tightening surface pressure is not feasible.

Sizes by customer request. Please refer to our brochure.

This gasket offers stable sealing performance even with a low surface pressure because of the elasticity, resilience, and conformability of its rubber.
