K94 is a single acting wiper ensuring that foreign particles are not introduced into the hydraulic system.
PRODUCT ADVANTAGES
•Very good wiping performance
•Simple , easy-construction groove
•No twisting in the house
•Specially designed to prevent hydrodynamic pressure build-up
•Specially designed to provide excellent sealing against big particles , humidity and water
•Used in heavy conditions by the good mechanical properties of Polyurethane material
APPLICATION
Mining industry , heavy-duty , concrete pumps , mobile applications , telescopic cylinders.
INSTALLATION
Easily installed to closed type groove. We recommend using special assembly tool (See section; Hydraulic Sealing Elements General Installation Information). It is very important that the assembly tools must be of soft material and have no sharp edges.
