Full Technical Description

1 1/2 ID HOS 2670 6671 26 is a heavy-duty hydraulic hose with 1 1/2 inch inner diameter, engineered for high-pressure fluid transfer on Epiroc and Atlas Copco drilling rigs, ROC-series machines, and underground jumbos. This hose is designed to safely convey hydraulic oil between pumps, valves, cylinders, and motors operating under extreme vibration, pressure pulses, and harsh mining conditions.

The 1 1/2 ID HOS 2670 6671 26 is manufactured using multi-layer reinforced construction with high-tensile steel wire braiding and oil-resistant synthetic rubber lining. Its abrasion-resistant outer cover protects against rock dust, moisture, mechanical impact, and hydraulic oil exposure, ensuring long service life in underground and surface drilling applications.

In operation, this hose maintains stable flow and pressure delivery, supporting smooth movement of feed systems, boom functions, rotation units, and auxiliary hydraulic circuits. Hose degradation or internal damage may lead to pressure loss, external leakage, or sudden hose rupture, which can cause machine downtime and safety risks if not addressed promptly.

During installation, ensure correct routing, minimum bend radius compliance, secure clamping, and clean hydraulic connections. Regular inspection for abrasion, swelling, cracking, or fitting loosening is recommended as part of preventive maintenance on drilling equipment.
