K42 HYDRAULIC COMPACT SEAL

K42 is a five piece double acting compact seal which consists of one multiple lipped elastomeric nitrile rubber sealing element , two polyester elastomer back-up rings on both sides to prevent extrusion into the sealing gap and two special profiled thermoplastic guide rings to absorb transverse forces.

PRODUCT ADVANTAGES
• Effective sealing during vibration and shock loading
• Superior sealing efeect in high pressures
• Maximum sealing effciency with the least amount of friction
• Superior sealing performance

APPLICATION
Heavy duty cylinders , excavators , cranes , marine hydraulics and loading platforms.

Note: It is recommended to have 50% to 90% of the working surface material contact area value.
INSTALLATION K42 compact seal must be used in open housing due to the non split form of the back-up ring produced from TPE material. If it is necessary to have a closed groove , back-up rings should be cut with 45° angle in a way not to have any gap and installed afterwards. On this case after the assembly onto the piston the cut on the back-up ring should be checked carefully. 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 For special applications that require high temperatures , piston seal is manufactured in FKM and PTFE material.
