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.

Bidirectional high-pressure ball valve seat seal is a type of seat sealing that can withstand bidirectional pressure, with good low-temperature performance and airtightness, and is widely used in 6D ball valves.

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.

Pack off seal or Secondary Seal Assemblies is installed in the lower seal area of the Casing Spool or Tubing Head.

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.

V-Packings are used in various Oilfield Downhole equipment such as various Valves etc. V-Packings are extremely suitable for usage in medium to heavy duty applications. Vee Packings accept low and high pressure while operating in the most extreme conditions and also if there exists any misalignment between the sealing gaps.

Pumpdown plugs separate cement from the displacement fluid during liner cementing operations.
