Product Overview

The 07000-12070 O-RING is a genuine Komatsu OEM replacement O-ring. O-rings seal hydraulic, fuel, and cooling system connections throughout your machine — compressing into precision grooves to block pressurized fluid from escaping between mating components.

When to Replace

• Leak visible at the sealed connection — oil, fuel, or coolant weeping from the joint
• O-ring hard, cracked, or showing a permanent flat spot from compression set
• Cuts, nicks, or extrusion damage visible on the seal surface
• Joint opened for service — O-rings must be replaced at every disassembly

Installation

1. Confirm 07000-12070 matches the old seal
2. Clean the groove — old seal fragments cause immediate leaks
3. Lubricate with clean oil — helps the O-ring seat without rolling
4. Position without twisting — a rolled O-ring leaks upon pressurization
5. Tighten to specified torque
