• Two-wire steel braid reinforcement – provides superior impulse life (over 1 million cycles).
• Oil-resistant synthetic rubber tube – compatible with mineral oils, synthetic hydraulic fluids, and water-glycol.
• Precision crimped fittings – eliminate leak paths and withstand high vibration.
• Color-coded layline – identifies pressure rating and manufacturing date for traceability.

The 380800386 steel-braided hose assembly is used in critical hydraulic circuits of XCMG motor graders: implement lift cylinders, steering valve supply lines, brake accumulator charging, and fan drive motors. It is the original equipment on GR2003, GR215, and GR180 models, and serves as a direct replacement for older GR series machines (2005 onward).

Typical applications include heavy road construction, mining overburden removal, landfill compaction, and large-scale agricultural grading. The hose assembly is also suitable for use on XCMG wheel loaders and excavators that share the same hydraulic interface, making it a cross-fleet spare part.

Each 380800386 hose assembly is manufactured in an ISO 9001 and IATF 16949 certified facility. The production process includes: material verification, in-process dimensional checks, proof pressure testing (at 1.5x working pressure), and impulse testing per SAE J343 (1.2 million cycles at 133% working pressure). Random samples are also tested for burst pressure, adhesion, and low-temperature flexibility.

XCMG guarantees that every 380800386 steel-braided hose assembly provides trouble-free service for at least 8,000 operating hours under normal grading conditions. Each assembly is stamped with the OEM number, production week, and a unique barcode for full traceability.

Before installing the 380800386 hose assembly, inspect the fittings for any damage and clean the mating ports. Apply a thin film of clean hydraulic oil to the O-rings or flare seats. Tighten the swivel nuts by hand until snug, then torque to 35–40 Nm using a crowfoot wrench. Do not twist the hose during installation; allow it to assume its natural lay.

Inspect hoses every 500 hours for signs of cover abrasion, kinking, or leakage. Replace immediately if the steel braid is exposed or if the fitting shows movement relative to the hose. Always store spare hose assemblies in a cool, dry place away from ozone and UV light.

XCMG is committed to reducing environmental impact. The 380800386 hose assembly is manufactured using lead-free rubber compounds and recyclable steel wire. The crimping process is energy-efficient, and scrap material is reclaimed. At end-of-life, the steel braid and fittings can be recycled as ferrous scrap, while the rubber can be processed into energy recovery or industrial mats.

By choosing genuine XCMG hose assemblies, you support sustainable manufacturing and reduce the frequency of replacement, thus lowering overall waste.

Aftermarket hose assemblies often use inferior rubber compounds and generic crimping that leads to premature failure or fitting blow-off. Genuine 380800386 guarantees OEM-specified materials, precise crimping geometry, and certified pressure ratings. Each authentic XCMG hose is labeled with the OEM number and the XCMG logo for easy identification.

With XCMG’s global logistics network, the 380800386 steel-braided hose assembly is available for rapid delivery to any job site. Protect your grader’s hydraulic system and maximize uptime by insisting on authentic XCMG components.

In summary, the XCMG Steel-Braided Hose Assembly OEM 380800386 is the definitive hydraulic line replacement for GR series motor graders. Its two-wire steel braid construction, precision crimped fittings, and wide temperature tolerance deliver unmatched reliability. Maintenance teams can depend on the 380800386 to eliminate leaks, prevent downtime, and extend component life. Upgrade your parts inventory with the original XCMG 380800386 – the hose assembly engineered for the toughest grading environments.
