KOMATSU 07000-F3022 O-RING

The Komatsu 07000-F3022 O-Ring is a genuine sealing ring engineered for the hydraulic systems of some of Komatsu’s largest earthmoving machines, including the D475A/D575A dozers and the PC1100/PC1250 excavator lines. It’s fitted into pump housings, cylinders, or hydraulic fittings, where it holds fluid under high pressure while keeping dirt, debris, and moisture from finding their way into the system — a role that matters even more on machines pushing this much hydraulic force through their circuits.

Manufactured to Komatsu’s OEM specifications, this O-Ring is molded from a rugged elastomer compound built to resist breakdown from hydraulic oil, grease, sustained pressure, and the heat that builds up during heavy, continuous operation. The material stays flexible instead of hardening or cracking, so it keeps forming a tight seal through long duty cycles rather than degrading unevenly. Tight manufacturing tolerances keep the fit accurate and repeatable, which matters on large-frame equipment where even small sealing gaps can lead to noticeable pressure loss.

On machines the size of the D575A or PC1250, hydraulic failures aren’t cheap to fix, which is exactly why using a genuine seal instead of a rough equivalent pays off. Replacing this O-Ring at the right service interval helps prevent slow leaks, keeps hydraulic pressure stable, and protects the pumps and cylinders it supports from premature wear.
