Oil & Gas Outer BOP Seal

JST's Inner and Outer BOP Seals could be made according to customer requirements. These seals are used in various type of Blow Out Preventors (BOP's).

SPGW is a high performance, double acting compact piston seal, to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.

OD Face Seals for gate valves are spring-loaded, pressure-energized lip seal that improve gate and seat service life.

JST's RGD (Rapid Gas Decompression) o ring can be applicated in high and low temperature environment with high pressure. It is widely used in detection and drilling equipment, completion equipment, underwater valves and pumps, compressor ect.

Wear rings are used to help keep the piston centered, allowing for even wear and pressure distribution on the seals. Wear rings are used in both piston and rod applications.

Spring energized valve stem packing contributes to the overall performance of industrial operations. They serve the vital task of keeping oil and liquids in while keeping contaminants out.

Liner Wiper Plugs separates drilling fluid from cement during displacement.

This is sealing product developed by JST to meet the increasingly demanding sealing needs of equipment manufacturers and users in semiconductor, petrochemical, mechanical seal, instrumentation, energy, biopharmaceutical, food and medical industries.
