800143982 o-ring XCMG XE2000 excavator spare parts

XCMG Original Excavator O-ring 800143982 – Key Sealing and Protection Component for XE2000 Model

If you need to replace the O-rings on your XCMG XE2000 excavator, the XCMG genuine O-ring with part number 800143982 is the preferred choice. As a “sealing barrier” for the XE2000’s hydraulic, lubrication, and fuel systems, it is mainly used for static sealing of joints, valve bodies, cylinders, and other parts to prevent oil and gas leaks. It is a core component for construction companies and excavator maintenance teams to ensure leak-free equipment operation.

Why choose XCMG XE2000 original O-ring 800143982?

1. Original factory precise fit, seamless seal

Designed strictly according to the original factory dimensions of each sealing component of the XE2000, the inner diameter, wire diameter, and cross-sectional accuracy are perfectly matched with the sealing groove, allowing for direct installation without trimming or adjustment. This avoids problems such as poor sealing and deformation caused by dimensional deviations of universal O-rings, ensuring a tight fit with the sealing surface and eliminating the risk of leakage at the source.

2. Made of oil-resistant rubber, durable and anti-aging.

Made from imported nitrile rubber (NBR) raw materials, it has oil resistance that meets the ASTM D1415 standard and can withstand the corrosion of hydraulic oil, engine oil, and diesel oil commonly encountered in XE2000 operations. It also has excellent anti-aging and temperature resistance properties, maintaining elastic stability in working conditions from -40℃ to 120℃, and is not prone to hardening or cracking. Its service life is 40% longer than that of ordinary rubber O-rings, reducing the cost of frequent replacements.

3. Precision vulcanization process, resulting in strong sealing performance.

Made through high-temperature and high-pressure vulcanization, the rubber has uniform density, a smooth surface free of bubbles and impurities, and a compression set of less than 20% (GB/T 7759 standard). After installation, it can maintain its compressive elasticity for a long time. Even under vibration and pressure fluctuations, it can still tightly fill the sealing gaps, effectively preventing oil leakage and avoiding failures such as insufficient system pressure and component wear caused by leakage.

Fully adaptable to various scenarios

The 800143982 O-ring plays a crucial sealing role in multiple operating conditions of the XE2000:
Heavy-duty mining applications: Resistant to high-pressure hydraulic oil impact, seals hydraulic pumps and cylinder joints, preventing oil leakage from affecting power output;
Earthwork for infrastructure: Suitable for long-term operation, with sealed lubrication system pipe interfaces to prevent lubricant leakage that could cause dry friction of components;
Construction: Resistant to frequent start-stop vibrations, seals fuel system valves to prevent fuel leaks from causing safety hazards;
Agricultural and forestry operations: Resistant to moisture and dust erosion, the rubber material has strong stain resistance and maintains stable sealing performance over a long period of time.

Flexible procurement: Supports single-pack retail (10/20 pieces per pack) and bulk wholesale, providing suitable quotations for repair shops and distributors to meet different inventory needs.

The sealing of each system in the XE2000 is the “bottom line” for stable operation of the equipment. The original O-ring 800143982, with its precise fit, oil-resistant material and reliable sealing performance, builds a leak-free barrier: reducing downtime due to failure, lowering maintenance costs, extending system life, and ensuring efficient operation.
