Oil Scraper Seal for Scrap Excess Lubricating Oil

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.

EVZ is commonly used in high-pressure mud pumps and fracturing pumps, namely Packings, the high-speed reciprocating dynamic seals.

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.

Nylon BX R RX style Test Ring Gasket is good for valve pressure test. JST Nylon ring joint test gaskets are a no damaging method to test and re-certify ring type joint flanges.

FFKM O-ring is a circular seal made of perfluoroelastomer compound, with a higher fluorine content than FKM fluoroelastomer.

Swivel joint ball plug is working together with hammer union seals, to seal the balls of high pressure elbows and grease.

DKBI 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.

The bonded seal is used in work-over and sand control operations. With the bonding of elastomer to a steel core, this serve to prevent excessive rubber compression under loading.
