Bonded seals for completion tools

Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.

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.

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.

Outer wireline valve seals are used in various type of Blow Out Preventors (BOP's).

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.

Dovetail groove is used to put the O-ring or elastomer dovetail seal during installation. This groove is not common because it is more expensive to machine, but this dovetail groove can avoid seal extrusion out.

JST's centralizer rubber fins is made according to customer requirements. The centralizer fin has a retrievable, reseatable, flexible design. This Rubber and metal reinforced rubber centralizer fins are available for a variety of MWD (measurement while drilling) tools and oil well logging and monitoring instruments.

The FDR seal is made of a helical wound spring and a polymer jacket, which is mainly used as a Flange external face seal.
