The genuine XCMG 380600532 Tube is a precision‑formed steel hydraulic tube used in motor grader steering, brake, and implement hydraulic circuits. This OEM 380600532 tube carries high‑pressure oil between pumps, valves, and cylinders. Manufactured from seamless cold‑drawn steel with a corrosion‑resistant zinc‑nickel plating, it withstands working pressures up to 28 MPa (4,000 psi). Engineered for XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders, this tube is a direct replacement for original equipment with identical bends, end flares, and mounting brackets.
A cracked, kinked, or corroded hydraulic tube causes oil leakage, pressure loss, and erratic machine control. Replacing a damaged tube with genuine XCMG 380600532 restores full flow, prevents fluid loss, and ensures safe, reliable operation of steering and braking systems.
This tube is also used in transmission cooler lines and pilot control circuits. XCMG 380600532 guarantees OE bend radius, exact length, and double‑flare or O‑ring boss end connections for leak‑free assembly.

The 380600532 tube is a rigid hydraulic line that conveys pressurized oil to steering cylinders, brake valves, and implement controls. Unlike flexible hoses, tubes offer greater burst resistance and dimensional stability under high pressure.
In steering circuits, this tube ensures immediate response when the operator turns the wheel. A cracked tube causes loss of steering assist, creating a dangerous condition.
Replacing a damaged tube with genuine XCMG 380600532 restores precise flow, eliminates external leaks, and maintains factory‑specified pressure drop across the circuit.
The tube’s double flare ends create a metal‑to‑metal seal with the fitting body, preventing weeping even under severe vibration.
Each 380600532 tube is cold‑drawn from seamless steel, then CNC bent on a mandrel bender to achieve the exact contour without kinking or ovality.
Ends are double‑flared on a hydraulic flaring machine, and the flare faces are lapped to a smooth finish. The tube is then cleaned and zinc‑nickel plated to resist rust inside and out.
XCMG hydrostatically tests each tube at 1.5× working pressure for 5 minutes. The plating is validated for 480 hours of salt spray resistance per ASTM B117.
All tubes are 100% visually inspected for surface defects, with random samples cut and examined for wall thickness uniformity.
To replace a leaking or corroded tube, relieve hydraulic pressure and drain the affected circuit. Use a backup wrench on the fitting body to avoid twisting the tube.
Remove the old tube and inspect the mating ports for damage. Clean the threads and flare seats. Install the new 380600532 tube by hand‑starting the nuts, then torque the JIC nut to 40 Nm and the ORFS nut to 35 Nm.
Bleed the circuit by running the engine and exercising the steering or brake function. Check for leaks immediately after pressurization.
Never reuse a damaged tube or attempt to straighten a bent tube – it will have weakened and may fail under pressure. Keep a spare 380600532 tube for emergency field replacement.
Visible rust pitting on the outside, deep scratches from abrasion, leaking from a flare joint (after retorquing), and tube crushed or kinked from impact.
Also, if the tube has been bent in service or shows signs of fatigue cracking near the end flares. Replace immediately to avoid sudden rupture and oil spray.
Inspect all rigid hydraulic tubes every 1,000 operating hours or during each oil change. Look for corrosion, chafing, and loose mounting clamps.
XCMG recommends replacing the 380600532 tube every 6,000‑8,000 hours or when any external corrosion exceeds 0.5 mm depth. In coastal or salt‑spray environments, replace every 4,000 hours.
Ensure that rubber isolators are present at all mounting points – missing isolators cause tube‑to‑frame chafing and premature failure.
When replacing the tube, also replace any damaged flare nuts and apply anti‑seize on the threads to prevent galling during future disassembly.
Genuine XCMG 380600532 tubes are backed by a 12‑month warranty. Regional warehouses: Houston (USA), Rotterdam (Netherlands), Dubai (UAE), Shanghai (China).
Standard air freight delivers within 3‑7 business days worldwide. Express 24‑48 hour shipping available for urgent repairs. Bulk orders (10+ tubes) receive volume discounts and sea freight options.
Aftermarket tubes often use welded seam tubing, have inaccurate bends, or lack the correct end flares, causing leaks and alignment problems. Genuine XCMG 380600532 ensures seamless steel, precision bends, and proper flare geometry.
Don’t risk a hydraulic oil leak leading to loss of steering or brakes. Keep a genuine spare tube in your parts inventory for quick field replacement.
