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).

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.

High pressure Rotary Seals is one bidirectional rotary seal which can bear both sides of pressure and alternating pressure.

Perfluoroelastomer (FFKM) O-rings have carbon fluorine bonds, making them one of the most thermally stable, oxidative stable, and chemically stable fluorinated polymers.

Piston seals are work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.

JST's back up ring compensate for large temperature fluctuations. Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. Back-up Rings are protective and supporting elements with no sealing function. The back up ring material could be  PEEK, modified PTFE.

JST ESY series design is commonly used as dynamic seal for ball valve stem, and the ESY with various V rings and T shape support rings could be used for fugitive emission valves, meeting the requirements of ISO-15848.

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.
