The 380600511 Pipe is a genuine XCMG hydraulic steel tube assembly designed for motor grader brake and steering circuits. This precision-formed pipe ensures leak-free fluid transfer between the master cylinder and wheel brakes. The 380600511 pipe is manufactured from cold-drawn seamless steel tubing, rated for high pressure and impulse resistance. It is a critical component for maintaining safe braking and precise steering on GR series graders.
The 380600511 Pipe is manufactured to DIN 2391 / EN 10305-1 standards, with a working pressure of 250 bar (3625 PSI) and a burst pressure of 1000 bar (14500 PSI). The tube ends are flared and fitted with precision nuts using a 360-degree swaging process to prevent blow-offs under impulse conditions. The assembly includes a straight male flare fitting on one end and a 90° swivel elbow on the other, allowing easy routing along the chassis frame.
Engineered for extreme durability, the 380600511 Pipe has an operating temperature range of -40°C to +120°C, suitable for all climates. The outer surface is zinc-plated and passivated, 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 pipes eliminates the risk of improper bending or wrong length, which can cause premature failure and safety hazards.

Aftermarket pipes often use lower-grade steel or incorrect bending radii, leading to kinking or fatigue cracks. The genuine 380600511 Pipe from XCMG is manufactured in a certified ISO 9001 facility with 100% pressure testing. Finite element analysis confirms that the bend geometry is optimized for the tube wall thickness, ensuring no stress risers. This reliability translates to fewer breakdowns and lower operating costs.
Each 380600511 Pipe is traceable to its production batch, with records of the tube heat number and flaring parameters. The pipe is stamped 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 pipes to 1 million pressure cycles at 133% of working pressure. Only pipes that pass this rigorous test are shipped.
Installation of the 380600511 Pipe requires care to avoid twisting. Before installation, route the pipe to determine the natural lay. Tighten the swivel nut to 30 Nm (22 ft-lbs) for the JIC fittings. Do not use sealant on the flare faces. Ensure the pipe does not contact sharp edges or hot surfaces; use protective sleeving if necessary. The minimum bend radius of 60mm must be respected to prevent tube collapse.
Inspect the 380600511 Pipe every 500 hours for signs of corrosion, leaks, or fitting damage. Replace immediately if any zinc plating is worn through or if the pipe shows dents. When replacing, always change the corresponding pipe on the opposite side (if applicable) to maintain balanced performance. Store spare pipes in a dry, covered area away from moisture.
A corroded or incorrectly bent pipe causes flow restriction and brake lag. The genuine 380600511 Pipe restores original flow characteristics, improving braking power and steering precision. Operators report consistent pedal feel and shorter stopping distances. The pipe’s smooth bore also minimizes pressure drop, ensuring quick response times.
In a field study of 20 XCMG GR215 graders, replacing all brake circuit pipes with genuine 380600511 Assemblies reduced stopping distances by 18% and eliminated spongy pedal feel. The improved reliability saved an average of 6 labor hours per machine per year in leak repairs and fluid top-ups. For contractors with large fleets, standardizing on OEM pipes simplifies inventory and lowers total cost of ownership.
XCMG’s tube bending plant uses CNC mandrel benders with real-time angle monitoring. The 380600511 Pipe is cut to length within ±0.5mm, and the ends are deburred using a high-speed rotary tool. Flaring is performed with a double-stroke hydraulic press to ensure consistent flare angle. The fittings are zinc-plated for corrosion resistance, and the tube is electro-coated for added protection.
All 380600511 Pipes 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 pipes can be delivered to any location within 5-7 business days, minimizing downtime for fleet repairs.
The 380600511 Pipe directly replaces original part numbers 380600510 and 380600512. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders manufactured from 2010 onward. This pipe is used in the brake line from the master cylinder to the front axle on most models. For the rear brake circuit, refer to part 380600513. Always verify the fitting orientation and length before ordering.
When replacing a failed pipe, also inspect the mating fittings and replace any damaged O-rings. XCMG recommends changing the brake fluid (DOT 4) and bleeding the system if the pipe was leaking. Keep one spare 380600511 Pipe in your service truck to avoid unplanned downtime. For fleet operators, bulk orders of 10 or more pipes 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 also provide pipes with DIN or SAE flares. Always provide your grader’s serial number and a photo of the original pipe when ordering the 380600511 Pipe to ensure perfect fitment.
