Specifications

What It Fits

Replaces Komatsu OEM part 07002-11023 wherever it is used on Komatsu hydraulic systems, fittings, pumps, valves and cylinders. Confirm the part number against your parts book or the machine's parts catalog.

You Can Do This Repair

Relieve hydraulic pressure and lower all implements before loosening any fitting. Remove the old o-ring with a plastic pick, clean the groove, lubricate the new ring with clean hydraulic oil, and seat it without twisting. Tighten the fitting to its normal torque.

Pro Tip: Order a few extras. Hydraulic o-rings are single-use once compressed, and having spares on the shelf turns the next leak into a ten-minute job.
