HNBR S seal for downhole application

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.

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.

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.

Oil-free Air compressor PTFE piston cup seals extensively used for steam, oil, water, and other chemical applications.

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

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.

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

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.
