XCMG Spare Parts O RING 39.34X2.62 803393170

This is a genuine XCMG O-ring seal (part #803393170), precision-engineered to the exact dimension 39.34mm × 2.62mm. Made for direct replacement in XCMG construction machinery, it follows strict OEM standards to guarantee perfect fit and reliable sealing performance.

Crafted from high-grade nitrile rubber (NBR), the O-ring delivers strong resistance to hydraulic oils, diesel fuel, and wear. It maintains stable elasticity and sealing integrity under long-term pressure, effectively preventing leaks in hydraulic and pneumatic systems.

Designed for static sealing and low-speed dynamic applications, this seal fits standard grooves in XCMG excavators, loaders, and other heavy equipment. Its tight tolerance control ensures easy installation and consistent compression in the groove.

The O-ring operates reliably under -30°C to 120°C working temperatures. It resists compression set, aging, and chemical corrosion, reducing maintenance frequency and extending service intervals on the job site.

As an authentic XCMG spare part, 803393170 ensures full compatibility with your machine. It’s a critical sealing component to protect hydraulic systems, minimize downtime, and keep equipment running at peak efficiency.
