Oil and Gas pumping equipment is the lifeline of hydraulic fracking and drilling operations. When pumps go down for planned or unplanned repairs, productivity comes to a halt. JST sealing profile can make the equipment run longer and more efficient.

Well Service Packing（ plunger packing seal） was developed to eliminate extrusion and provide excellent abrasion resistance for fracturing, acidizing, and cementing pumps; and it delivers maximum seal ability for high-pressure well service pumps.

Well Service Packing is made from high quality materials for extended service life in all applications. We provide various compounds for all types of environments, including high pressure, abrasive and high temperature.

JST manufactures well service pump packings in a wide variety of materials to suit specific well conditions and operating parameters.

• Material Range: NBR, HNBR, FKM, filled PTFE, fabric reinforced rubber.

• Compatible with a wide range of fracturing fluids.

• Available as complete assemblies that include spacer and lantern ring.
