Bonded seals for completion tools

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.

We have been manufacturing various types of fluid end valve and seats for both frac pumps and mud pumps, covering various models for the most dominant pumps in the market.

Phenolic wear rings are designed with tubing made from fine weave cotton fabric wound on molds and imbued with phenolic resin. It has high mechanical properties, good oil resistance, low water absorption and high wear resistance.

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.

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.

The oil scraper ring is a part located at the rear of the pump packing seal.

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.

Hammer Union Seals are used in hammer union-style pipe connections to establish flow lines and prevent leakage. It is widely used in the oil & gas industry.
