PTFE guide and wear strip

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.

T-seals are three piece seals with an elastomeric lip and hard plastic anti-extrusion rings, it is proved to be of long time service. The standard design will fit into an o-ring gland and can be machined or net moulded.

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.

Back-up Ring/Anti Extrusion Rings is a ring that holds an elastomeric seal to its outline shape and in its right place. and are typically used with O Rings to eliminate extrusion at high pressures.

JST's Inner and Outer BOP Seals could be made according to customer requirements. These seals are used in various type of Blow Out Preventors (BOP's).

PDR rotary shaft seal extends the boundaries of elastomeric radial shaft seals, utilizing advanced materials and design techniques to provide optimal sealing performance for each application. The result is a superior sealing solution that retains a compact sealed casing.

OD Face Seal are 100% compatible with Cameron Type FLS and FLS-R Gate Valves, It is spring-loaded and pressure-energized to improve gate and seat service life.

JST FHP series is  made of a helical wound spring and a polymer jacket, which is mainly used for piston.
