The 800374378 Sealing Ring is manufactured from premium elastomers with precision‑moulded geometry, ensuring consistent sealing force, excellent compression set resistance, and reliable performance across every unit.
Its carefully engineered lip profile maintains constant contact with the mating surface, providing a positive seal that prevents leakage even under pressure fluctuations and vibration.
The material selection – NBR or FKM – is tailored to the specific fluid and temperature requirements, offering broad compatibility with mineral oils, synthetic fluids, and air.
The ring’s robust construction resists extrusion and deformation, ensuring long‑term sealing integrity even in high‑pressure hydraulic circuits and pneumatic systems.
The low compression set ensures that the seal retains its original shape and elasticity over extended service intervals, preventing leakage due to permanent deformation.
In demanding applications such as open‑pit mines, aggregate quarries, and heavy construction sites, the 800374378 delivers reliable, long‑lasting sealing for your ADT’s fluid systems.
The 800374378 sealing ring is produced using advanced injection moulding and post‑curing processes, achieving tight tolerances on inner diameter, cross‑section, and surface finish.
The elastomer compound is precisely mixed and vulcanised to optimise physical properties, ensuring consistent hardness, tensile strength, and compression set resistance.
After moulding, each ring undergoes 100% dimensional inspection, visual inspection, and hardness verification to ensure it meets the required specifications.
Sample units from each production batch are subjected to compression set testing, fluid immersion testing, and thermal cycling to validate long‑term durability and performance.
All materials are RoHS compliant and free from hazardous substances, meeting stringent environmental standards.
This rigorous manufacturing and inspection protocol ensures that every 800374378 sealing ring delivers the performance and reliability demanded by XCMG’s global customer base.
Articulated dump trucks rely on a multitude of sealing rings to contain hydraulic fluid, compressed air, and lubricants, making the quality of each seal vital to overall machine reliability and safety.
The 800374378 sealing ring serves as a critical barrier in hydraulic cylinders, valve blocks, and pneumatic actuators, preventing fluid loss and contamination ingress.
A substandard or worn seal can lead to fluid leakage, pressure drop, system contamination, and catastrophic component failure — risks that are eliminated by using genuine XCMG seals.
Field data from mining operations shows that ADTs equipped with genuine XCMG sealing rings experience 50% fewer fluid‑related failures and a 30% reduction in unscheduled maintenance, directly improving machine availability and safety.
The seal’s precise dimensional control and excellent compression set resistance ensure consistent sealing performance, reducing the risk of oil leaks and environmental contamination.
Regular inspection of sealing rings for signs of wear, cracking, or extrusion is recommended; any compromised rings should be replaced promptly with genuine 800374378 components.
The 800374378 sealing ring is available in both nitrile (NBR) and fluoroelastomer (FKM) compounds, providing an exceptional combination of oil resistance, heat resistance, and durability.
NBR offers excellent resistance to mineral oils, greases, and hydraulic fluids, with a temperature range of -40°C to +120°C, making it suitable for most ADT applications.
For higher temperature or chemically aggressive environments, FKM provides superior resistance to heat, acids, and synthetic lubricants, with a temperature range of -20°C to +150°C.
Both materials exhibit low compression set and excellent elasticity, ensuring long‑term sealing effectiveness and resistance to permanent deformation.
The sealing ring’s smooth surface finish reduces friction and wear on mating components, extending the life of both the seal and the hardware.
With proper installation and routine maintenance, the 800374378 sealing ring can provide reliable service for the entire lifespan of the ADT, reducing the need for premature replacements.
The 800374378 sealing ring is specifically designed to fit XCMG’s full range of articulated dump trucks, including the XDA30, XDA40, XDA45, XDA45U, XDA60, and TA30 models, as well as their respective variants and hydraulic/pneumatic configurations.
Its dimensions, cross‑section, and material specifications are identical to the original factory‑fitted component, ensuring a direct, drop‑in replacement without the need for modifications.
The seal is compatible with XCMG’s standard hydraulic fluids, lubricants, and pneumatic systems, simplifying inventory management and reducing the risk of incorrect part selection for fleet operators.

The 800374378 sealing ring is designed for quick and simple installation using standard workshop tools, minimising downtime and labour costs during routine servicing or component replacement.
Before installation, carefully inspect the sealing ring for any signs of damage, deformation, or contamination that may have occurred during storage or transport, and ensure that the gland and mating surfaces are clean, smooth, and free from burrs.
Lubricate the sealing ring lightly with clean system fluid or a compatible grease to facilitate installation and prevent damage during assembly.
Position the ring carefully in its groove, ensuring it is not twisted or over‑stretched, and confirm that it sits evenly without protruding from the groove.
During routine maintenance, inspect the sealing ring for signs of wear, hardening, cracking, or extrusion, and replace it if any damage is detected.
Always handle sealing rings with clean, lint‑free gloves to prevent contamination of the sealing surface.
Investing in the genuine 800374378 sealing ring delivers significant long‑term savings by preventing fluid leaks, reducing contamination, and avoiding costly system failures that can result from seal degradation.
A single hydraulic leak due to a failed seal can cost over $1,000 in lost fluid, cleanup, and labour — a risk that is virtually eliminated with OEM‑quality seals.
