K703 is a two piece single acting wiper which consists of one special designed PTFE profile ring and an o-ring as energizing element. K703 ensures that foreign particles are not introduced into the hydraulic systems , avoiding wear and damage to all the internal components including seals.
PRODUCT ADVANTAGES • Low friction , free of stick-slip • Long service life • High sliding speed • Space-saving construction • Wide range of temperature and chemicals depending on the o-ring material • Wide range of dimensions
APPLICATION Mobile hydraulics , aluminum injection machines and industrial equipment.

Note: It is recommended to have 50% to 90% of the working surface material contact area value
INSTALLATION 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. Before installation the sealing element must be oiled with system oil.
NOTES When K703 wiper is being used with double lip sealing element we recommend a pressure relieving bore between the seal and wiper. For special applications that require high temperatures or resistance to chemicals , piston seal is being manufactured with special mixture PTFE and FKM material.
