Spring energized PTFE lip seal

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.

The spring energized seal is widely used in medical equipment, which is generally composed of a corrosion resistant spring and a seal ring made of U-shaped filled PTFE/UPE material.  

Wellhead secondary pack off seal is used to seal the hanger to the wellhead.

XTP is Double acting piston seals, composed of PTFE piston sealing ring, O-ring and X ring, and is used for the piston bidirectional seal of hydraulic cylinder. Especially suitable for separating two different mediums.  

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.

FFKM O-rings provide the highest temperature (up to 620 ° F) and most common chemical resistance among all rubber O-ring and gasket materials.

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.

Piston seals are work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
