Bonded seals for completion tools

Rod seals are static seals installed in glands or housings to prevent the leakage of fluid from within a cylinder to the outside as the rod cycles.

Spring energized PTFE seals consist of variety of jacket profiles and spring types. It can achieve the sealing effect compensation under different pressure conditions by spring energizer.

SPGO is a low friction piston seal consisting of PTFE+Bronze seal ring and rubber o-ring used for two-way piston seal of Hydraulic cylinder, to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.  

Many industries use FFKM O-rings in critical applications where sealing failure is strictly prohibited. These industries include chemical processing, energy, semiconductors, pharmaceuticals, oil and gas recovery, aerospace, and other industries.

JST manufactures well service plunger pump packings in a wide variety of materials to suit specific well conditions and operating parameters, they are available in a wide range of elastomeric materials and high performance resins, including NBR, HNBR, FKM, filled PTFE, fabric reinforced rubber.  to suit specific well conditions, operating parameters, and fracturing fluids.

FFKM O-rings provide the highest temperature (up to 620 ° F) and most common chemical resistance among all rubber O-ring and gasket materials.

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.

The JST valve insert seal is mainly used for sealing valve seat of fracturing pump. It is made of modified polyurethane material of excellent extrusion resistance, puncture resistance and fatigue resistance, which guarantees the fracturing work under various working conditions.
