K34 is a three piece single acting sealing set which consists of one reinforced cotton fabric or thermoplastic elastomer back-up ring , one specially designed multiple lipped elastomeric nitrile rubber sealing element and one thermoplastic anti-extrusion ring.

PRODUCT ADVANTAGES
• Effective sealing during vibration and shock loading
• Improved sealing gap due to the active anti-extrusion ring
• Superior sealing effect in high pressures
• Alternative design to packings

APPLICATION
Earth moving equipment , excavators , cranes , loading platforms , and special machinery.

Note: It is recommended to have 50% to 90% of the working surface material contact area value.

 

INSTALLATION
Assembly into the open grooves. If it is necessary to have a closed groove , back-up ring should be cut with 75° angle in a way not to have any extrusion gap and installed afterwards. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation all individual parts of the seal must be oiled with system oil.

 

NOTES
For special applications that require high temperatures , our seal set is being manufactured in the following configuration , FKM header ring , back-up ring and anti-extrustion rings from special mixture of PTFE material.
