Downhole MWD centralizer rubber fins

The V Stack seal assembly is comprising a top adapter or anti-extrusion ring (1), Vee Rings (2) and a bottom adapter (3). In the assembly the energizing axial force is transferred between the individual packing rings so that each ring is pressed into positive contact with the mating hardware surface. Special material grades are available for a large variety of working conditions. The chevron seal stack material could be PEEK, modified PTFE and spring.

The ESA valve rubber seal is a type of Polypak, it combines a rubber o-ring type and a conventional lip type seal to produce a unique sealing device.

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.

The bonded seal is used in work-over and sand control operations. With the bonding of elastomer to a steel core, this serve to prevent excessive rubber compression under loading.

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).

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.

Bidirectional high-pressure ball valve seat seal is a type of seat sealing that can withstand bidirectional pressure, with good low-temperature performance and airtightness, and is widely used in 6D ball valves.
