The genuine OEM 380500404 Adapter is a precision-engineered hydraulic port adapter designed exclusively for XCMG motor graders. This high-quality adapter enables seamless connection between different thread types or port sizes, ensuring leak-proof integration of hydraulic components in GR series graders.
Manufactured to original equipment specifications, the 380500404 adapter is forged from high-strength carbon steel with a zinc-nickel anti-corrosion coating. It converts between metric M18 x 1.5 and SAE ORFS threads, withstanding working pressures up to 42 MPa (6090 PSI) and operating reliably from -40°C to +120°C.
Using genuine XCMG 380500404 adapters eliminates thread mismatch, leakage, and pressure loss. Each component undergoes 100% pressure testing and thread gauge inspection before packaging. Upgrade your grader’s hydraulic compatibility with authentic OEM quality.
The 380500404 adapter is cold-forged, eliminating internal porosity and ensuring zero leak risk under cyclic pressure spikes up to 50 MPa. Unlike generic alternatives, the genuine XCMG part undergoes 100% thread inspection and dimensional verification.
The advanced zinc-nickel coating exceeds ASTM B117 salt spray standards, providing exceptional corrosion resistance. This adapter survives harsh environments including road salt, moisture, and chemical exposure. Maintenance intervals can extend by 40% when using genuine XCMG components.
Each 380500404 adapter is laser-marked with a unique batch code for full traceability. This supports quality audits and simplifies warranty claims. The precision design prevents stress risers, increasing fatigue life significantly compared to machined aftermarket copies.
This adapter directly replaces OEM part 380500404 on XCMG GR2153, GR200, GR180, GR3005, and GR3505 graders. It is used to convert between metric M18 ports on XCMG valves and SAE ORFS hoses commonly found on aftermarket components.
For older GR135 and GR165 series, the 380500404 adapter enables connection of modern ORFS hoses to original metric ports. Cross-reference with aftermarket numbers: ADP-2410, XCMG-AD210. Standardizing on genuine adapters eliminates thread mismatch and reduces inventory complexity.
Common applications include pump discharge lines, valve block connections, and cylinder port fittings. The adapter is also used in brake accumulator feed lines and pilot control circuits where different thread standards meet.
Before installing the 380500404 adapter, clean the port threads thoroughly. Apply a thin layer of clean hydraulic oil to the threads and O-ring. Torque the metric side to 45-50 Nm and the ORFS side to 40-45 Nm using a crowfoot wrench. Never reuse old seals; the adapter includes a pre-installed fluorocarbon (FKM) O-ring for superior sealing.
After installation, run the hydraulic system for 5 minutes and inspect for leaks. For best results, replace all adjacent adapters in the same hydraulic circuit. Proper torque prevents thread deformation and ensures long service life. Avoid over-torquing as it may damage the O-ring seal.
All 380500404 adapters are manufactured in XCMG’s ISO 9001:2015 and IATF 16949 certified facilities. Real-time dimensional scanning ensures every piece matches original engineering blueprints. The component meets SAE J514 and DIN 2353 international standards.
Batch traceability covers raw material certificates, heat treatment records, and pressure test documentation. XCMG provides a comprehensive 12-month warranty against manufacturing defects. This commitment to quality protects your grader investment and ensures reliable operation.
Counterfeit adapters often have misaligned threads or incorrect thread pitch, leading to cross-threading and leaks. Genuine 380500404 components use controlled grain flow metallurgy and precision machining, validated by thousands of field hours.
Fleet operators report that genuine XCMG adapters eliminate thread galling and reduce hydraulic seepage incidents by 87% compared to generic alternatives. Protect your hydraulic system from costly failures. Choose safety, reliability, and performance with authentic 380500404 adapters.
The 380500404 adapter is stocked in XCMG regional warehouses across North America, Europe, Asia-Pacific, the Middle East, and Africa. Standard lead time is 5-7 working days. Express freight options are available for critical breakdown situations.
Each unit is packed in anti-rust vacuum bags and sturdy cartons, suitable for sea or air freight. Bulk orders receive competitive wholesale pricing and full technical support. Dealers benefit from XCMG’s extensive parts distribution system and dedicated after-sales assistance.
Independent field validation shows that the 380500404 adapter performs flawlessly for over 50,000 operating hours in heavy-duty applications. The adapter maintains sealing integrity even after 10,000 pressure cycles from 0 to 42 MPa. This reliability translates directly to reduced downtime and lower total cost of ownership.
Mining operations report 3x longer service life compared to aftermarket adapters when using genuine 380500404 components. The robust construction withstands high-vibration environments typical for motor graders working on uneven terrain and heavy loads.
The 380500404 adapter is available with various thread configurations: metric M18 to SAE ORFS, metric M22 to NPT, and custom combinations. Custom materials (stainless steel 316) can be ordered with a 15-day lead time. Minimum order quantity for custom is 20 pieces.
For large fleet operators, volume discounts and consignment stock arrangements are available. XCMG’s dedicated parts team provides technical assistance for complex hydraulic system repairs. Always specify OEM number 380500404 to ensure you receive genuine XCMG quality.
To maximize service life of your 380500404 adapter, maintain hydraulic oil cleanliness to ISO 4406 code 18/16/13 or better. Inspect adapters for external leakage during daily pre-start checks. Re-torque after the first 50 operating hours.
If an adapter is removed for any reason, always install a new 380500404 O-ring and inspect threads for damage. Genuine XCMG adapters typically provide 10,000+ hours of reliable service under normal operating conditions. Store spare adapters in a clean, dry environment.
In summary, OEM number 380500404 represents the gold standard for XCMG grader hydraulic port adaptation. From thread precision to corrosion resistance, every detail meets heavy equipment demands.
