Product Overview

The 17A-09-11180 O-RING is a genuine Komatsu OEM replacement O-ring from the 17A prefix series. O-rings seal connections throughout your machine's hydraulic, fuel, and cooling systems — they compress between two components to block pressurized fluid from escaping.

When to Replace

• Leak visible at the sealed connection
• O-ring hard, cracked, or showing compression set
• Cuts, nicks, or extrusion on the seal surface
• Joint opened for service — O-rings are single-use seals

Installation

1. Confirm 17A-09-11180 matches the old seal
2. Clean the groove thoroughly — debris creates a leak path
3. Lubricate with clean oil to help it seat
4. Position without twisting — a rolled O-ring leaks under pressure
5. Tighten to specified torque
