50Hydraulic rod seal PTFE SPNS step seal
SPNS type hydraulic seals, are also call rod buffer step seals, static seals installed in glands or housings to prevent the leakage of fluid from within a cylinder to the outside as the rod cycles.
SPNS seals can be applied to various applications, especially those occasions where polyurethane seals are not suitable for applications, such as oil in water or emulsion media. PTFE materials have extremely low friction, corrosion resistance and heat resistance compared with other known sealing materials, However, compared with polyurethane and other rubber sealing materials, PTFE is hard and has poor elasticity. In order to make full use of the advantages of PTFE, PTFE must be matched with an expansion ring to supplement elasticity as a seal. At the same time, the PTFE slip ring must be reasonably designed, and the expansion ring must provide sufficient initial sealing force and ensure its static sealing function in the groove.

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.
Piston seals are work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
BS seal is rod seal for hydraulic cylinders, single-acting, polyurethane u-cup design with secondary sealing lip.
This product can fully meet the pressure working conditions of current hydrogen compressor transportation equipment, ranging from 0 to 90MPa, and the sealing element will not extrude and deform, with good sealing performance.
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.
Liner Wiper Plugs separates drilling fluid from cement during displacement.
DKBI 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.
ptfe wear strips can keep the piston centered as well as preventing metal-to-metal contact.
