The 802164445 Seal is a genuine XCMG elastomeric O‑ring engineered to deliver reliable, long‑lasting fluid containment in the hydraulic cylinders, valve assemblies, and power train components of articulated dump trucks and heavy mining equipment.
This OEM seal, identified by part number 802164445, is manufactured from a high‑grade nitrile (NBR) compound that provides excellent resistance to mineral oils, greases, and moderate heat, making it ideal for standard hydraulic and lubrication circuits.
Designed to withstand the harsh conditions of mining, quarrying, and construction, the 802164445 seal ensures leak‑free operation, reducing downtime and preventing environmental contamination from fluid spills.
Its precision‑molded dimensions and consistent durometer guarantee a perfect fit in standard gland grooves, restoring original equipment sealing performance with every replacement.
The 802164445 Seal is a precision‑molded nitrile O‑ring that provides effective, durable sealing in a wide range of hydraulic and pneumatic applications on XCMG articulated dump trucks.
This genuine OEM seal is designed to fit standard AS568 gland grooves, delivering consistent compression and reliable fluid containment even under fluctuating pressures.
The nitrile rubber compound offers excellent resistance to petroleum‑based fluids, making it the preferred choice for hydraulic oil, engine oil, and transmission fluid sealing.
Its 70 Shore A hardness provides the optimum balance between sealing force and ease of installation, reducing the risk of extrusion or damage during assembly.
A compromised seal can lead to costly leaks and system contamination. The 802164445 seal eliminates these risks with proven, long‑lasting performance.
In XCMG articulated dump trucks, nitrile O‑rings like the 802164445 are used extensively in hydraulic cylinders, valve banks, and drivetrain components to prevent fluid leakage and protect against dirt ingress.
These seals are critical for maintaining system pressure, ensuring that cylinders operate efficiently and that steering and braking functions remain responsive.
Without reliable sealing, hydraulic oil can escape, leading to pressure loss, erratic operation, and increased wear on pumps and actuators.
The 802164445 seal is engineered to withstand the thermal cycling, pressure spikes, and vibration common in mining and construction equipment, providing consistent sealing integrity.
Its nitrile compound also resists swelling and hardening, maintaining its sealing profile over thousands of operating hours.
The 802164445 seal features a precision‑molded, circular cross‑section with a smooth surface finish that minimizes friction and wear during dynamic movement.
Manufactured in a high‑cavity, flash‑free molding process, each seal is dimensionally consistent, ensuring a perfect fit in the gland groove without over‑compression.
The nitrile compound is formulated with anti‑oxidants and anti‑ozonants to resist environmental degradation, extending service life even in harsh outdoor conditions.
The seal’s 70 Shore A durometer provides enough stiffness to resist extrusion under high pressure, yet remains flexible enough to conform to minor surface irregularities.
Its compatibility with standard lubricants and hydraulic fluids makes it a versatile choice for multiple applications across the machine.
The 802164445 seal is manufactured from a premium nitrile butadiene rubber (NBR) compound that offers an excellent balance of oil resistance, temperature stability, and mechanical strength.
The polymer is cross‑linked with sulfur to achieve the desired hardness and elasticity, while special fillers enhance abrasion resistance and tear strength.
The material exhibits low compression set, meaning it returns to its original shape after being compressed, maintaining sealing force over time.
It is also resistant to mild acids, alkalis, and water‑based fluids, making it suitable for applications where occasional coolant or moisture ingress may occur.
This advanced formulation ensures that the 802164445 seal delivers consistent performance across a wide range of operating conditions.
The 802164445 seal is used extensively across XCMG articulated dump trucks and other heavy machinery operating in surface and underground mining, as well as large‑scale civil construction.
It is commonly installed in hydraulic cylinder end caps, valve body O‑ring grooves, accumulator ports, and brake caliper pistons.
The seal’s ability to handle moderate pressures and temperatures makes it ideal for steering cylinders, suspension accumulators, and transmission oil circuits.
Its robust nitrile construction resists the abrasive dust and debris present in mining environments, preventing premature wear.
The 802164445 seal is also a direct replacement for many standard O‑rings used in other XCMG equipment, including wheel loaders and excavators.
Every 802164445 seal is produced in an ISO 9001‑certified facility, with rigorous quality control at every stage of manufacturing.
Incoming raw materials are tested for viscosity, cure rate, and physical properties to ensure consistency.
During molding, each seal is inspected for flash, voids, and dimensional accuracy using automated vision systems.
Finished seals are subjected to hardness, tensile, and compression set tests per ASTM D2000 to verify performance.
100% visual inspection ensures that every seal is free from surface defects that could compromise sealing integrity.
This comprehensive quality assurance guarantees that the 802164445 seal meets XCMG’s strict standards for reliability and safety.
The 802164445 seal is a direct OEM replacement for the original O‑ring on XCMG articulated dump trucks, including models XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, AD45, AD60, and other variants.
Its dimensions (38 mm ID × 3.53 mm CS) conform to AS568‑116 standard, making it compatible with a wide range of existing gland designs.
When replacing a worn seal, the 802164445 ensures a perfect fit and proper compression, restoring the system’s leak‑free operation.
For cross‑brand applications, verify the groove dimensions, pressure, and temperature ratings to ensure compatibility.
Always consult the parts manual to confirm the correct seal for your specific component.
Correct installation of the 802164445 seal is essential to ensure leak‑free performance. Begin by cleaning the groove and mating surfaces thoroughly, removing any debris or old sealant.
Inspect the groove for burrs, sharp edges, or corrosion that could damage the seal. Lightly deburr if necessary.
Apply a thin, even layer of hydraulic oil or assembly lubricant to the seal and groove to reduce friction during installation.
Gently roll the seal into the groove, ensuring it is not twisted or over‑stretched. The seal should sit evenly with no protrusions.
After assembly, check that the seal is correctly positioned and that the mating parts are aligned. Pressurize the system gradually to verify no leaks.
During routine maintenance, inspect the seal for signs of hardening, cracking, or extrusion. Replace immediately if any damage is observed.
Regularly monitor fluid quality, as degraded oil can accelerate seal degradation.
The 802164445 seal complies with ASTM D2000 (Material Specification M2BG710), meeting the requirements for oil resistance, heat resistance, and low‑temperature flexibility.
