The 800370369 Hose is a genuine XCMG hydraulic line assembly designed for motor grader brake circuits, steering systems, and implement pilot lines. This precision‑manufactured hose carries pressurized oil from the master cylinder or control valve to wheel brakes and steering actuators on XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders.
Constructed from a synthetic rubber inner tube, two high‑tensile steel wire braids, and an abrasion‑resistant outer cover, the 800370369 hose withstands working pressures up to 21 MPa (3,045 psi). Factory‑crimped swivel fittings with O‑ring seals ensure leak‑free performance under extreme vibration, temperature swings, and exposure to road salts and moisture.
A burst, cracked, or leaking hose can cause sudden loss of braking or steering, creating a serious safety hazard. Replacing a worn hose with genuine XCMG 800370369 restores full hydraulic integrity, protects operators, and prevents costly downtime. The hose meets SAE 100R2AT and ISO 1436 standards, and is impulse‑tested to 1,000,000 cycles at 133% of rated pressure.
Using genuine XCMG guarantees perfect fitment, correct end fitting angles, and superior durability. Never repair a damaged hose – always replace with the OEM 800370369 assembly.

The XCMG 800370369 Hose is a vital link between the brake master cylinder and the wheel brake actuators. It delivers pressurized hydraulic fluid instantly when the operator presses the brake pedal.
A failed hose can cause a complete loss of braking, making the grader unsafe to operate. The 800370369 is constructed with two steel braids that withstand repeated pressure spikes without bursting.
In steering circuits, this hose connects the steering control valve to the steering cylinder. Any leak or restriction leads to heavy steering feel or loss of directional control.
The 800370369 is also used for pilot lines on blade lift and circle drive valves. Its smooth inner tube ensures consistent pilot pressure, giving precise implement control.
Regular inspection of this hose is essential for grader safety. Replace any hose showing cracks, bulges, or chafing before it fails.
Each 800370369 hose assembly is manufactured in XCMG’s ISO 9001 certified facility using automated spiral braiding and vulcanization processes.
The steel wire is drawn to exact tensile strength and braided at a 54° angle to maximize pressure capacity while maintaining flexibility.
After braiding, the outer rubber is extruded and cured in autoclaves with precise temperature profiling to ensure uniform wall thickness.
Each assembly undergoes 100% high‑pressure proof testing at 31.5 MPa (150% of rated working pressure) with real‑time leak detection.
The crimped ferrule diameter is checked with laser micrometers; any deviation beyond ±0.1 mm is rejected. The 800370369 also passes impulse testing to 1 million cycles.
A unique batch code is laser‑etched on each hose for traceability back to raw materials. Counterfeit hoses rarely meet these standards.
XCMG provides a 12‑month warranty against manufacturing defects. Choose genuine for safety and reliability.
Replacing a failed hydraulic hose begins with relieving system pressure. Shut off the engine and pump the brake pedal or move steering wheel to release residual pressure.
Clean the area around both fittings to prevent contamination. Disconnect the old hose using proper wrenches, capturing any spilled oil.
Compare the new 800370369 assembly with the old one – verify length, end fitting angles, and thread size. Always install new O‑rings supplied with the genuine assembly.
Route the new hose exactly as the original, avoiding sharp edges, exhaust components, and moving linkages. Use original clamps or nylon ties to prevent chafing.
Hand‑tighten the fittings, then torque to specification: M16 × 1.5 fittings to 35‑40 Nm (25‑30 ft‑lb). After installation, refill brake or steering fluid if necessary.
Start the engine, bleed the system if required, and check for leaks at idle and under full operation. If leaks occur, re‑torque or replace the seals.
XCMG recommends full hose replacement every 4,000 hours or five years, whichever comes first. Keep spare 800370369 assemblies in your parts inventory.
Aftermarket hoses often use low‑grade rubber that hardens and cracks within months, leading to sudden burst under pressure.
Many generic assemblies have incorrect ferrule crimping dimensions causing fitting blow‑offs. The genuine 800370369 features XCMG‑specified crimp geometry.
Aftermarket hoses frequently have smaller inner diameters, restricting flow and slowing brake or steering response.
Counterfeit hoses rarely pass flame resistance or impulse tests. They degrade internally, sending rubber particles into valves.
XCMG’s 800370369 includes a one‑year warranty, while aftermarket units offer no coverage. Protect your investment with original parts.
For fleet operators, using OEM hoses reduces total cost of ownership by minimizing unplanned breakdowns and hydraulic component wear.
Don’t risk safety – insist on XCMG genuine 800370369 for brake and steering circuits.
Watch for these symptoms indicating the 800370369 hose needs replacement: visible cracks or blisters on the rubber cover, leaking fluid at fittings, a soft or spongy feel when squeezing the hose, and hydraulic oil puddles under the grader.
Also, if the brake pedal feels spongy or steering becomes heavy, internal hose delamination may be restricting flow.
During daily inspections, run a dry cloth along the hose to detect seepage. Check for chafing marks where the hose contacts frame brackets.
Replace any hose that shows exposed steel braid or deep cuts. Proactive replacement is recommended at 4,000‑hour intervals.
The cost of a genuine 800370369 is negligible compared to a crash caused by brake failure or a hydraulic pump ruined by debris.
Implement a 2,000‑hour hose rotation program for critical circuits. This reduces unexpected failures by 60% based on XCMG fleet data.
Always clean hose ends before reconnection to prevent dirt ingress. Store spare hoses in a cool, dry area away from ozone sources.
