The genuine OEM 803164724 Fitting is a precision-engineered hydraulic connector designed specifically 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, delivering uncompromised reliability in the most demanding construction environments.
Manufactured to original XCMG specifications, the 803164724 fitting is forged from high-strength carbon steel with a corrosion-resistant zinc-nickel coating. It withstands working pressures up to 42 MPa (6090 PSI) and operates reliably from -40°C to +120°C, making it ideal for demanding grading environments including mining, road construction, and winter maintenance.
Using genuine XCMG 803164724 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 that matches the original equipment fitted at the XCMG factory.
The 803164724 fitting is produced using multi-stage cold heading, which preserves material grain flow and enhances fatigue resistance. Unlike generic fittings, this OEM component features a radiused thread root and a precision-machined seating surface that eliminates stress risers, ensuring structural integrity under continuous high-frequency pressure pulsations.
The advanced zinc-nickel coating exceeds ASTM B117 salt spray standards, providing exceptional corrosion protection for over 500 hours of continuous exposure. This coating ensures the 803164724 fitting survives harsh environments including road salt, moisture, and chemical exposure, extending maintenance intervals by up to 40% compared to standard zinc-plated alternatives.
Each 803164724 fitting is laser-marked with a unique batch code for full traceability, supporting quality audits and simplifying warranty claims. The bonded washer is made of NBR rubber bonded to a steel backing ring, ensuring consistent compression and sealing even after repeated installation cycles.
This fitting directly replaces OEM part 803164724 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 used throughout the XCMG motor grader lineup.
The 803164724 fitting is typically installed on the main hydraulic pump discharge line, steering control valve inlet, and brake accumulator charge port. It also secures cylinder hoses on blade lift and circle drive circuits. Proper fitting selection prevents thread galling, which can ruin expensive valve blocks.
Standardizing on genuine XCMG 803164724 fittings reduces inventory complexity and ensures consistent performance across your fleet. Common applications include pump discharge lines, valve block connections, and cylinder port fittings, as well as brake accumulator feed lines and pilot control circuits.
Before installing the 803164724 fitting, clean the female port threads and inspect for burrs or old seal remnants. Apply a drop of medium-strength thread locker (Loctite 243) for vibration-prone areas. Hand-tighten the fitting until the bonded washer contacts the face, then torque to 45–50 Nm using a calibrated torque wrench. Do not exceed 55 Nm to avoid distorting the washer.
For O-ring port versions, lightly lubricate the O-ring with clean hydraulic oil and torque to 35–40 Nm. After installation, run the hydraulic system for 5 minutes and inspect for leaks. Re-torque after the first 50 operating hours. When replacing the fitting, always install a new bonded washer or O-ring.
During scheduled maintenance (every 500 hours), inspect fittings for signs of leakage, rust, or thread damage. Replace immediately if the hex corners are stripped or plating is compromised. Never reuse old seals or attempt to repair a damaged fitting.
All 803164724 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. Each fitting undergoes 100% thread inspection, pressure testing at 63 MPa, and helium leak detection before packaging.
Random samples from each batch are subjected to vibration testing (1.5 million cycles at 50 Hz) with no loosening or leakage. Salt spray testing (500+ hours) validates corrosion resistance. Batch traceability covers raw material certificates, heat treatment records, and pressure test documentation. XCMG provides a comprehensive 12-month warranty against manufacturing defects.
Counterfeit fittings often cause thread galling, internal collapse, or sudden leaks that lead to expensive pump failures. Genuine 803164724 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 803164724 fittings.
