JST offers a wide range of molded elastomer (rubber) products for exploration, drilling, and well-service applications.
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.
JST manufactures a complete size-range of elastomer-to-metal bonded seals. We use an exclusive two-phase manufacturing process to produce highly-reliable bonded seals capable of controlling either conventional wellbore fluids or exotic media. By using bonding processes, we overcame the problems customarily associated with bonding NBR, HNBR, FKM or Aflas to corrosion resistant metal and can provide seals for various temperature ranges and/or H2S applications. The metal frame like 20# steel, 8620, 4140 are commonly used.
JST can provide the best sealing types and materials for various oil and gas drilling and exploration applications, so as to maximize the service life and performance of the sealing system.

The ID S seal is used for wellheads, downhole tools and surface pressure control equipment as a critial part.
Wear rings are used to help keep the piston centered, allowing for even wear and pressure distribution on the seals. Wear rings are used in both piston and rod applications.
Piston seals are working to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
The seal jacket of adhesive dispenser/dispensing seal is made of ultra-high molecular UHMWPE or PEEK, with installed stainless steel anti-corrosion spring with low temperature resistance treatment.
S Seals are well suited for sealing wellheads, connectors, downhole tools, high pressure valves and other demanding oil and gas applications. The non-extrusion springs can be fabricated from different metals.The S seal is made of spring and rubber material could be NBR, HNBR, FKM ect.
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.
The ESA valve rubber seal is a type of Polypak, it combines a rubber o-ring type and a conventional lip type seal to produce a unique sealing device.
In LNG operations, valves can regularly encounter temperatures below -320 F (-196 C) and pressures above 750 pounds per square inch (psi). They are also subjected to periodic variations in temperatures known as “thermal cycling,” which can result in hardware expansion as well as shrinkage and material stresses. These factors make reliable, long-term valve operation an engineering challenge.
