description

O-ring rubber seal is static sealing part for bulldozer and pipelayer flanges, pipe connectors and valve blocks. It fills clearance by compression deformation to retain fluid and block muddy water and metal debris. Aging, cracking, extrusion damage and permanent compression set will lead to oil leakage, unstable pressure and accelerated wear of gears and bearings.

Application Scenarios

Fits Caterpillar D8L, D9L, D9N, D9R, D10N, D10R track-type tractor and 589 pipelayer, used for sealing overhaul of final drive, transmission, hydraulic valve and pipe joints.

FAQ 

Q：Can the O-ring with slight oil seepage continue to be used?
A：Not recommended. Rubber has lost compression, leakage will get worse and contaminants may damage gears and bearings.

Q：Can I reuse the intact O-ring after removal?
A：No. Permanent compression deformation occurs, sealing reliability drops sharply after reinstallation.

Q：Can ordinary grease be used for assembly lubrication?
A：No. Only compatible grease is allowed. Incompatible grease causes rubber swelling and premature failure.

Q：Will new O-ring work if the groove is worn?
A：Poor effect. Oversized groove gap squeezes the O-ring and causes re-leakage soon, repair or replace housing first.
