Rod wiper seals 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.
When the equipment is stationary (stationary, the connecting rod has no reciprocating motion) and in use (dynamic, reciprocating connecting rod), the hydraulic pu wiper seals remain in contact with the seal of the piston rod, and the tolerance of the connecting rod diameter is determined by the connecting rod seal. If there is no wiper seal, the retracted piston rod may deliver pollutants to the cylinder.
The external static seal of the wiper seal in the housing is also important to prevent moisture or particles from entering the outside of the wiper seal.

DLI is a dust resistance and oil-scraping double acting seal. Consist of PU and iron material.
KZT is used in combination with anti-wear and piston ring to prevent cylinder oil from mixing with foreign particles, avoiding seal damage.
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.
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.
V-Packings are used in various Oilfield Downhole equipment such as various Valves etc. V-Packings are extremely suitable for usage in medium to heavy duty applications. Vee Packings accept low and high pressure while operating in the most extreme conditions and also if there exists any misalignment between the sealing gaps.
VT type V Packing is widely used for sealing pistons and rods with both single and double acting cylinders.
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.
Spring energized valve stem packing contributes to the overall performance of industrial operations. They serve the vital task of keeping oil and liquids in while keeping contaminants out.
