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.  

JST's RGD (Rapid Gas Decompression) o ring can be applicated in high and low temperature environment with high pressure. It is widely used in detection and drilling equipment, completion equipment, underwater valves and pumps, compressor ect.

Pack off seal or Secondary Seal Assemblies is installed in the lower seal area of the Casing Spool or Tubing Head.

Hammer union seals are used for hammer joint type pipe connections to establish flow lines and prevent leakage.

This is sealing product developed by JST to meet the increasingly demanding sealing needs of equipment manufacturers and users in semiconductor, petrochemical, mechanical seal, instrumentation, energy, biopharmaceutical, food and medical industries.

SPGW is a high performance, double acting compact piston seal, to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.

It is an end face spring energized seal with both rigid and flexible elements, which gives consistent contact at the sealing interface.
