Rubber V Packing hydraulic seals

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.

The valve stem packing is an essential component of valves, which is covered around the valve stem. The purpose of valve packing is to prevent leakage.

JST FHR series is  made of a helical wound spring and a polymer jacket, which is mainly used for rod.

JST's centralizer rubber fins is made according to customer requirements. The centralizer fin has a retrievable, reseatable, flexible design. This Rubber and metal reinforced rubber centralizer fins are available for a variety of MWD (measurement while drilling) tools and oil well logging and monitoring instruments.

KZT is used in combination with anti-wear and piston ring to prevent cylinder oil from mixing with foreign particles, avoiding seal damage.

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.

Perfluoroelastomer (FFKM) O-rings have carbon fluorine bonds, making them one of the most thermally stable, oxidative stable, and chemically stable fluorinated polymers.

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.
