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.  

Lockdown screw seal is used mainly in geothermal applications, HNBR packing with stainless steel caps provide superior performance over metal pressure seals.

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

SPGO is a low friction piston seal consisting of PTFE+Bronze seal ring and rubber o-ring used for two-way piston seal of Hydraulic cylinder, 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 ball valve seat is responsible for sealing the fluid inside and uniformly distributing the seating stress. A leak of ball valve in petrochemical application could be environmentally devastating.

Hammer Union Seals are used in hammer union-style pipe connections to establish flow lines and prevent leakage. It is widely used in the oil & gas industry.

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.
