Komatsu Part HOSE 08671-51030

Product Overview

The 08671-51030 HOSE is a genuine Komatsu OEM replacement hose from the 08671 prefix series. Hoses are flexible fluid conduits that carry pressurized hydraulic oil, fuel, engine coolant, and lubricant between components while accommodating the constant movement, vibration, and thermal cycling of heavy equipment operation. Each OEM hose is manufactured with the correct inner tube compound for fluid compatibility, reinforcement layers rated for the system's working pressure, and end fittings crimped at the precise angle required for proper routing.

When to Replace

Replace the 08671-51030 when the outer cover shows cracking, bulging, or visible abrasion exposing the wire reinforcement; when leaks appear at either fitting end or through the hose wall; when the hose has soft, spongy, or blistered areas indicating internal tube failure; when kinked, crushed, or cut sections are present from impact or improper routing; or when the hose has reached Komatsu's recommended replacement interval. A burst hydraulic hose releases hot oil at high pressure — both a safety hazard and an environmental spill.
