The 801144671 Sealing Ring is a genuine XCMG elastomeric seal engineered to provide reliable fluid containment and contamination exclusion in critical hydraulic and pneumatic systems of articulated dump trucks. This OEM sealing ring, identified by part number 801144671, is manufactured from high‑performance FKM (fluoroelastomer) compound with a precision‑molded circular cross‑section. Designed to fit into standard O‑ring grooves, the 801144671 sealing ring delivers consistent compression, excellent chemical resistance, and long‑term sealing integrity. Its ability to withstand extreme pressures, temperatures, and aggressive media makes it an indispensable component for maintaining leak‑free operation in steering, brake, and powertrain circuits.
The 801144671 Sealing Ring is a precision‑engineered O‑ring that provides a static or dynamic seal between mating components in hydraulic and pneumatic systems.
This genuine XCMG sealing ring is designed to fit into standard gland grooves, compressing between two surfaces to create a barrier that prevents fluid escape and contaminant ingress.
Manufactured from high‑grade FKM (fluoroelastomer), the ring offers exceptional resistance to high temperatures, aggressive chemicals, and long‑term compression set.
The precise dimensional tolerances ensure a perfect seal without over‑compression, which could damage the ring or the mating surfaces.
A failed sealing ring can cause debilitating leaks, fluid contamination, and safety hazards. The 801144671 ring eliminates these risks with reliable, long‑lasting performance.
In XCMG articulated dump trucks, sealing rings like the 801144671 are used extensively in hydraulic cylinder pistons, valve blocks, accumulator ports, flange joints, and brake systems.
They provide the primary barrier that keeps high‑pressure hydraulic oil contained and prevents external contaminants from entering the system.
Without an effective seal, hydraulic pressure drops, system response becomes sluggish, and component wear accelerates due to contaminated fluid.
The 801144671 sealing ring is engineered to withstand the thermal cycling, pressure spikes, and vibration inherent in mining and construction operations.
Its robust elastomeric formulation ensures that it maintains its sealing force over extended periods, even with minimal maintenance.
The 801144671 sealing ring features a precision‑molded circular cross‑section with a smooth, defect‑free surface that ensures consistent compression and sealing performance.
The ring is manufactured using a high‑cavity tooling process that maintains tight dimensional control and eliminates flash or parting lines that could compromise sealing.
Its FKM material is formulated to resist swelling in petroleum‑based fluids, while maintaining elasticity at low temperatures to prevent brittle failure.
The ring’s hardness of 70 Shore A provides the optimal balance between sealing force and resistance to extrusion, even under high pressures.
The design also considers dynamic applications – the ring can accommodate minor axial or radial movement without losing its sealing capability.
The 801144671 sealing ring is produced from a premium fluoroelastomer compound that offers superior resistance to high temperatures, oxidation, and chemical attack.
This material retains its physical properties across a wide temperature range, from -30°C to +180°C, making it suitable for both arctic and tropical environments.
The FKM compound exhibits excellent resistance to compression set, meaning the ring maintains its shape and sealing force even after prolonged deflection.
It also resists swelling in the presence of hydraulic fluids, transmission oils, and diesel fuel, ensuring dimensional stability and leak‑free performance.
Advanced material science guarantees that the 801144671 sealing ring delivers consistent performance under the most severe operating conditions.
The 801144671 sealing ring is widely used in XCMG articulated dump trucks and other off‑highway machinery operating in surface mining, underground mining, and heavy construction.
It is commonly found in hydraulic cylinder piston seals, valve block O‑rings, accumulator port seals, flange gaskets, and brake caliper sealing applications.
The ring’s ability to withstand high pressures and aggressive fluids makes it ideal for use in steering systems, suspension circuits, and transmission controls.
In dusty, wet, and abrasive environments, the seal’s robust construction prevents particle ingress that could cause scoring or premature wear.
The 801144671 ring is also compatible with other XCMG equipment, including wheel loaders, excavators, and motor graders that use the same groove dimensions.
Every 801144671 sealing ring is manufactured in an ISO 9001‑certified facility under strict quality control procedures.
Raw FKM compounds are sourced from approved suppliers and tested for viscosity, cure rate, and physical properties before molding.
During molding, each ring is inspected for flash, sink marks, and dimensional accuracy using laser‑based measurement systems.
Finished rings are subjected to hardness testing, tensile strength verification, and compression set testing per ASTM D395.
100% visual inspection ensures that no surface defects, voids, or contamination are present. This guarantees that every 801144671 sealing ring meets XCMG’s rigorous standards.
The 801144671 sealing ring is designed as a direct replacement for the original O‑ring on XCMG articulated dump trucks, including models XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, AD45, AD60, and others.
Its dimensions (34.5 mm ID × 3.53 mm CS) conform to the AS568‑118 standard, making it interchangeable with many industry‑standard glands.
When replacing a worn seal, the 801144671 ring restores the system’s sealing integrity to factory levels.
For cross‑brand applications, verify that the groove dimensions, pressure, and temperature ratings are compatible.
Always consult the parts manual to confirm the correct seal for your specific application.
Proper installation of the 801144671 sealing ring is essential for achieving a leak‑free seal. Before installation, inspect the groove and mating surfaces for burrs, scratches, or corrosion.
Clean the groove and surrounding area with a lint‑free cloth and a compatible solvent to remove dirt, old sealant, or debris.
Lubricate the ring and the groove with a thin film of the system’s hydraulic fluid or a recommended assembly lubricant to prevent pinching or twisting during installation.
Gently roll the ring into the groove, avoiding over‑stretching, which can cause permanent deformation. Ensure the ring is seated evenly without twisting.
After assembly, check that the ring does not protrude beyond the gland surface and that all parts are correctly aligned.
During routine maintenance, inspect the ring for signs of hardening, cracking, swelling, or extrusion. Replace immediately if any damage is observed.
Regularly check fluid levels and quality, as degraded oil can accelerate seal aging.
The 801144671 sealing ring complies with international standards including ASTM D2000 (classification system for rubber materials) and SAE J200.
It meets the requirements for oil resistance, heat resistance, and low‑temperature flexibility specified for heavy‑duty off‑highway applications.
The materials used are free from restricted substances such as lead, cadmium, and polycyclic aromatic hydrocarbons (PAHs).
This ensures that the sealing ring is safe for operators and environmentally responsible.
Using genuine XCMG seals like the 801144671 also helps maintain compliance with equipment warranty and safety regulations.
Aftermarket sealing rings may appear similar, but they often use lower‑grade elastomers, inferior curing processes, or inaccurate dimensions that lead to premature failure.
The genuine 801144671 sealing ring is engineered specifically for XCMG equipment, ensuring perfect fitment, precise compression, and long‑term reliability.
Using genuine seals reduces the risk of leaks, system contamination, and costly downtime.
