The genuine OEM 803164255 Fitting is a precision-engineered hydraulic connector designed exclusively for XCMG motor graders. This high-quality fitting ensures leak-proof, high-pressure connections between hydraulic hoses, tubes, and critical system components in GR series graders.
Manufactured to original equipment specifications, the 803164255 fitting is forged from high-strength carbon steel with a zinc-nickel anti-corrosion coating. It withstands working pressures up to 42 MPa (6090 PSI) and operates reliably from -40°C to +120°C, making it ideal for the most demanding grading environments.
Using genuine XCMG 803164255 fittings eliminates thread galling, pressure loss, and costly hydraulic failures. Each component undergoes 100% pressure testing and thread gauge inspection before packaging. Upgrade your grader’s hydraulic reliability with authentic OEM quality.
The 803164255 fitting 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 fitting survives harsh environments including road salt, moisture, and chemical exposure. Maintenance intervals can extend by 40% when using genuine XCMG components.
Each 803164255 fitting 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 fitting directly replaces OEM part 803164255 on XCMG GR2153, GR200, GR180, GR3005, and GR3505 graders. It also retrofits older GR135 and GR165 series without modification. The thread geometry precisely matches steering cylinders, brake valves, hydraulic oil coolers, and implement control valves.
Cross-reference with aftermarket numbers: HYD-2210, 860112345. For fleet standardization, using genuine 803164255 fittings reduces inventory complexity. Ensure optimal hydraulic flow and component longevity by choosing OEM parts.
Common applications include pump discharge lines, valve block connections, and cylinder port fittings. The 803164255 is also used in brake accumulator feed lines and pilot control circuits.
Before installing the 803164255 fitting, clean the port threads thoroughly. Apply a thin layer of clean hydraulic oil to the threads and O-ring. Torque to 45-50 Nm using a crowfoot wrench. Never reuse old seals; the fitting 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 fittings 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 803164255 fittings 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 fittings often cause thread galling, internal collapse, or sudden leaks that lead to expensive pump failures. Genuine 803164255 components use controlled grain flow metallurgy and precision heat treatment. Field tests show that OEM fittings reduce hydraulic seepage incidents by up to 87% compared to generic alternatives.
The anti-vibration collar design prevents loosening under heavy ripping operations. Original XCMG parts maintain the resale value of your machinery. Always verify the OEM marking to avoid costly failures. Choose safety, reliability, and performance with authentic 803164255 fittings.
The 803164255 fitting 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 803164255 fitting performs flawlessly for over 50,000 operating hours in heavy-duty applications. The fitting 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 fittings when using genuine 803164255 components. The robust construction withstands high-vibration environments typical for motor graders working on uneven terrain and heavy loads.
The 803164255 fitting is available with various thread configurations: metric M18x1.5, M22x1.5, ORFS, and NPT. 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 803164255 to ensure you receive genuine XCMG quality.
To maximize service life of your 803164255 fitting, maintain hydraulic oil cleanliness to ISO 4406 code 18/16/13 or better. Inspect fittings for external leakage during daily pre-start checks. Re-torque flange bolts after the first 50 operating hours.
If a fitting is removed for any reason, always install a new 803164255 O-ring and inspect threads for damage. Genuine XCMG fittings typically provide 10,000+ hours of reliable service under normal operating conditions. Store spare fittings in a clean, dry environment.
In summary, OEM number 803164255 represents the gold standard for XCMG grader hydraulic connections. From thread precision to corrosion resistance, every detail meets heavy equipment demands.
