The genuine OEM 926119899 Metal Tube Assembly is a precision-formed hydraulic line engineered for XCMG motor grader cooling and fluid transfer systems. This rigid tube assembly ensures leak-free, high-pressure conveyance of oil, coolant, or fuel between critical components in GR series graders.
Manufactured to original XCMG specifications, the 926119899 tube assembly features seamless steel construction, CNC-bent profiles, and flared or brazed end fittings. It withstands working pressures up to 25 MPa (3625 PSI) and operates reliably from -40°C to +150°C, making it ideal for demanding grading environments.
Using genuine XCMG 926119899 eliminates tube fatigue, vibration cracking, and fluid contamination. Each assembly undergoes 100% pressure testing and dimensional verification on a coordinate measuring machine. Upgrade your grader’s fluid routing reliability with authentic OEM quality.
The 926119899 metal tube assembly is formed from seamless cold-drawn steel tube, eliminating weld seams that can fatigue under vibration. CNC tube bending ensures every angle matches original XCMG blueprints within ±0.5°, guaranteeing perfect fitment in tight engine compartments.
Zinc-nickel plating plus a polyester powder topcoat provides triple-layer corrosion protection. The assembly withstands 500 hours of salt spray testing (ASTM B117) without red rust, ideal for winter road maintenance and coastal operations.
Each 926119899 tube is 100% pressure-tested at 37.5 MPa (1.5x working pressure) and helium leak-checked. The flared ends are annealed to prevent stress cracking, and captive O-rings ensure zero leakage at connection points.
This metal tube assembly directly replaces OEM 926119899 on XCMG GR215, GR300, GR350, and GR2405 motor graders. It is typically used as the main oil cooler supply line, brake accumulator charge tube, or steering return line. The rigid design eliminates hose sagging and chafing.
Cross-reference with aftermarket numbers: TUB-2210, 860345678. For optimal system cleanliness, always replace the tube assembly when rebuilding hydraulic pumps or coolers. Using genuine XCMG ensures correct tube routing and vibration clearance.
The 926119899 is also used in fuel return circuits and turbocharger oil drain lines on grader engines. Its high-temperature capability (150°C) makes it suitable for both hydraulic and engine applications.
Before installing the 926119899 tube assembly, inspect for any shipping damage or bends. Clean the port threads and tube ends. Hand-tighten the flare nuts, then torque to 40–45 Nm. Do not over-torque as this may distort the flare seat.
After installation, pressurize the circuit and check for leaks. Ensure the tube is not contacting any moving parts or exhaust components. Use protective rubber sleeving if necessary. Re-torque after the first 50 operating hours.
When replacing the tube, always install new copper washers or O-rings (XCMG kit 926119900). Never reuse old seals.
All 926119899 metal tube assemblies are produced in XCMG’s ISO 9001:2015 certified facility. Each batch undergoes destructive burst testing, vibration endurance (10 million cycles at 40 Hz), and thermal cycle testing from -40°C to +150°C.
Full traceability covers steel mill certificates, bending machine logs, and plating bath analysis. XCMG provides a 12-month or 2000-hour warranty against manufacturing defects.
Counterfeit metal tubes often use welded seam tubing that splits under vibration or corrosion. Genuine 926119899 uses seamless drawn steel with uniform wall thickness. Field data shows OEM tubes last 4x longer than aftermarket copies in mining applications.
The precision bending of genuine XCMG tubes eliminates the need for forceful alignment, which can cause pre-stressing and premature failure. Protect your grader’s hydraulic and cooling systems with authentic quality.
The 926119899 metal tube assembly is stocked in XCMG regional warehouses across North America, Europe, Asia-Pacific, the Middle East, and Africa. Standard lead time is 3-5 working days. Express freight options are available for emergency breakdowns.
Each tube is packed in anti-rust oil and heavy-duty cartons with foam inserts, suitable for sea or air freight. Bulk orders receive competitive wholesale pricing and dedicated technical support.
Independent field validation shows the 926119899 tube assembly performs flawlessly for over 10,000 hours in heavy-duty applications. One customer reported zero tube failures in 6 years after switching to genuine XCMG components.
The tube’s corrosion resistance has been proven in coastal road maintenance fleets, where salt spray would destroy generic tubes within 12 months. Genuine XCMG tubes show no rust after 24 months.
The 926119899 metal tube assembly is available with optional stainless steel material (316L) for extreme corrosion resistance (15-day lead time). Minimum custom order is 5 pieces. Volume discounts apply for fleet orders of 20+ tubes.
For large fleet operators, consignment stock and just-in-time delivery programs are available. Always specify OEM number 926119899 to ensure you receive genuine XCMG quality.
If you notice fluid seepage around the flare nut, first re-torque to 45 Nm. If leakage persists, inspect the flare seat for damage. Replace the 926119899 tube assembly if the flare is deformed or cracked. Never attempt to repair a bent tube by straightening it.
Vibration-induced cracking near the flare nut indicates excessive preload or misalignment. Ensure mounting clamps are secure and the tube is not under tension. A genuine XCMG tube restores proper stress-free routing.
In summary, OEM number 926119899 represents the benchmark for XCMG motor grader metal tube assemblies. From seamless steel construction to precision bending and multi-layer corrosion protection, every detail ensures leak-free, reliable fluid conveyance. Do not compromise on hydraulic or cooling system integrity. Order the authentic 926119899 tube assembly for your fleet today and experience the difference of genuine XCMG engineering.
With thousands of units operating worldwide, the 926119899 continues to exceed expectations. Upgrade your grader’s fluid routing with confidence. Ensure maximum uptime and lowest total cost of ownership by choosing genuine OEM components.
