PTFE guide and wear strip

JST's back up ring compensate for large temperature fluctuations. Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. Back-up Rings are protective and supporting elements with no sealing function. The back up ring material could be  PEEK, modified PTFE.

High pressure Rotary Seals is one bidirectional rotary seal which can bear both sides of pressure and alternating pressure.

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

Outer wireline valve seals are used in various type of Blow Out Preventors (BOP's).

Many industries use FFKM O-rings in critical applications where sealing failure is strictly prohibited. These industries include chemical processing, energy, semiconductors, pharmaceuticals, oil and gas recovery, aerospace, and other industries.

Nylon BX R RX style Test Ring Gasket is good for valve pressure test. JST Nylon ring joint test gaskets are a no damaging method to test and re-certify ring type joint flanges.

The FDB seal is made of a helical wound spring and a polymer jacket, It is the best choice for vacuum, gas and low-temperature flange sealing applications.

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.
