800142725 o-ring XCMG XE2000 excavator spare parts

XCMG XE2000 Original O-ring (800142725) – A Precision Guardian of Hydraulic Seals
CMG XE2000 Dedicated O-ring | Part Number 800142725 | Guaranteed Zero Leakage and Perfect Sealing

In the hydraulic system of the XCMG XE2000 large excavator, the O-ring (800142725), though a small seal, plays a crucial role in preventing leaks. This genuine O-ring uses special rubber materials and precision manufacturing processes to provide your equipment with the most reliable sealing guarantee, ensuring the hydraulic system maintains optimal sealing under high pressure and high temperature conditions.

Why are genuine O-rings so important?

O-rings are the “sealing guardians” of hydraulic systems, and their core functions include:
1. Absolute sealing: Achieves zero-leakage sealing in the hydraulic system, maintaining stable system pressure.
2. Contamination Protection: Effectively prevents external contaminants from entering the hydraulic system.
3. Pressure and temperature resistance: Can withstand a maximum working pressure of 35MPa and a temperature range of -40℃ to 150℃.
4. Shock absorption and buffering: Absorbs system pressure fluctuations and mechanical vibrations.

Four Core Advantages of Choosing Original Part Number 800142725

1. Precision manufacturing process
• CNC molding is used, and dimensional tolerances are controlled within ±0.03mm.
• Smooth, burr-free surface ensures 100% sealing performance.
2. Guaranteed high-quality materials
• Made with imported hydrogenated nitrile butadiene rubber (HNBR), improving oil resistance by 50%.
• Temperature resistance range -40℃ to 150℃, extending service life by 3 times.
3. Excellent sealing performance
• After 1000 hours of durability testing, the leakage rate is less than 0.01%.
• Sealing performance is 70% better than ordinary O-rings.
4. Strict quality inspection
• Passed 500,000 pressure pulse tests
• After 500 hours of thermal aging testing, its quality meets aerospace-grade standards.

[Professional Advice]

Clean the sealing groove before installation to ensure no impurities remain. It is recommended to use a dedicated tool for installation to avoid scratching the sealing ring. Store in a cool, dry place away from direct sunlight and high temperatures to maintain material properties. Regularly check the seal, especially under harsh operating conditions. Replace the O-ring promptly after disassembly to ensure reliable sealing.
