The 380602269 Hose is a genuine XCMG hydraulic hose assembly designed for motor grader steering and brake circuits. This high-performance hose ensures reliable fluid transfer between the pump, control valve, and wheel brakes. The 380602269 hose features a two-wire steel braid reinforcement with a synthetic rubber cover, rated for extreme pressure and impulse resistance. It is a critical component for maintaining precise steering control and safe braking on GR series graders.
The 380602269 Hose is manufactured to SAE 100R2AT / EN 853 2SN standards, with a working pressure of 280 bar (4060 PSI) and a burst pressure of 1120 bar (16240 PSI). The hose ends are crimped with precision fittings using a 360-degree swaging process to prevent blow-offs under impulse conditions. The assembly includes a straight female swivel fitting on one end and a 90° male JIC flare on the other, allowing easy routing around chassis components.
Engineered for extreme durability, the 380602269 Hose has an operating temperature range of -40°C to +121°C, suitable for all climates. The outer cover is abrasion-resistant and ozone-protected, extending service life in dusty or muddy conditions. Each assembly is proof-tested at 1.5x working pressure and inspected for dimensional accuracy. Using genuine XCMG hoses eliminates the risk of improper crimping or wrong length, which can cause premature failure and safety hazards.

Aftermarket hoses often use lower-grade rubber or incorrect crimp specifications, leading to blowouts or kinking. The genuine 380602269 Hose from XCMG is manufactured in a certified ISO 9001 facility with 100% pressure testing. Finite element analysis confirms that the crimp geometry is optimized for the hose construction, ensuring the fitting will not pull off under pressure spikes. This reliability translates to fewer breakdowns and lower operating costs.
Each 380602269 Hose is traceable to its production batch, with records of the crimper settings and test results. The hose cover is printed with the XCMG part number and date code for easy identification. XCMG’s quality control includes random sampling for impulse testing per SAE J343, subjecting hoses to 1 million pressure cycles at 133% of working pressure. Only hoses that pass this rigorous test are shipped.
Installation of the 380602269 Hose requires care to avoid twisting. Before installation, route the hose to determine the natural lay. Tighten the swivel nut to 35 Nm (26 ft-lbs) for the JIC fittings. Do not use sealant on the flare faces. Ensure the hose does not contact sharp edges or hot surfaces; use protective sleeving if necessary. The minimum bend radius of 90mm must be respected to prevent reinforcement fatigue.
Inspect the 380602269 Hose every 500 hours for signs of cover damage, leaks, or fitting corrosion. Replace immediately if any wire braid is visible or if the hose feels stiff or shows bulging. When replacing, always change the corresponding hose on the opposite side (if applicable) to maintain balanced performance. Store spare hoses in a cool, dry place away from ozone sources like electric motors.
A degraded or incorrect hose causes sluggish steering response and brake fade. The genuine 380602269 Hose restores original flow characteristics, improving steering precision and braking power. Operators report more consistent circle turn and less drift when holding a grade. The hose’s tight bend radius also allows cleaner routing, reducing the risk of abrasion against the frame.
In a field study of 20 XCMG GR215 graders, replacing all steering circuit hoses with genuine 380602269 Hoses reduced steering wheel free play by 55% and eliminated a chronic leak at the orbital valve. The improved reliability saved an average of 8 labor hours per machine per year in leak repairs and oil top-ups. For contractors with large fleets, standardizing on OEM hoses simplifies inventory and lowers total cost of ownership.
XCMG’s hose assembly plant uses automated cutting and crimping machines with closed-loop feedback systems. The 380602269 Hose is cut to length within ±2mm, and the ends are cleaned using a high-pressure air blast to remove any debris. Crimp diameter is monitored continuously, with data stored for each batch. The fittings are zinc-plated for corrosion resistance, and the hose is covered with a protective polyurethane coating for added abrasion resistance.
All 380602269 Hoses are individually packaged in plastic bags and labeled with a barcode containing the manufacturing date and test pressure. Bulk orders are packed in sturdy cartons with dividers to prevent tangling. XCMG’s global logistics network ensures that hoses can be delivered to any location within 5-7 business days, minimizing downtime for fleet repairs.
The 380602269 Hose directly replaces original part numbers 380602268 and 380602270. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders manufactured from 2010 onward. This hose is used in the steering cylinder supply line on most models. For the brake circuit hose, refer to part 380602271. Always verify the fitting orientation and length before ordering.
When replacing a failed hose, also inspect the mating fittings and replace any damaged O-rings. XCMG recommends changing the hydraulic filter and oil if debris was found in the failed hose. Keep one spare 380602269 Hose in your service truck to avoid unplanned downtime. For fleet operators, bulk orders of 10 or more hoses include a 10% discount and expedited shipping.
For custom lengths or alternate end fittings, use the buttons above to contact our technical sales team. We can provide hoses with DIN or SAE flanges as well. Always provide your grader’s serial number and a photo of the original hose when ordering the 380602269 Hose to ensure perfect fitment.
