High pressure swivel joint ball plug

JST's Packer elements are flexible elastomeric components that are used to seal between the outside diameter of the production tubing and the casing, liner or wellbore.

Easy installation rod seal is external seals that prevent leakage from the cylinder. EU rod seal for piston rods in pneumatic cylinders combines three functions: sealing-wiping-fixing.

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.

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

We have been manufacturing various types of fluid end valve and seats for both frac pumps and mud pumps, covering various models for the most dominant pumps in the market.

The FS-seal is a relatively large cross section spring energized elastomer casing and tubing hanger seal for wellheads that always has the springs on the internal surface.

OD Face Seals for gate valves are spring-loaded, pressure-energized lip seal that improve gate and seat service life.

The pump plunger sealing system is adopted in the pump, which can effectively prevent the damage caused by water leakage and prevent the pump failure caused by the plunger friction overheating.
