Downhole pump down plug (PDPC)

Piston seals are working to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.

Liner Wiper Plugs separates drilling fluid from cement during displacement.

Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.

V Packing consist of multiple male and female adaptor, usually a group of three to seven v rings, used for low or high pressure applications with Single or Double acting cylinder.

Dovetail groove is used to put the O-ring or elastomer dovetail seal during installation. This groove is not common because it is more expensive to machine, but this dovetail groove can avoid seal extrusion out.

The oil scraper ring is a part located at the rear of the pump packing seal.

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.

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