XCMG Spare Parts O RING 56X5.3 803197151

This XCMG genuine O-ring, part 803197151, is a direct replacement for the 56x5.3 size used across loader and excavator hydraulic systems. It’s not a universal seal—it’s cut to the exact spec XCMG calls for in original assembly.

You’ll find this one on pilot lines, valve banks, and cylinder end caps where a precise seal is critical. The 56mm inner diameter with a 5.3mm cross section fits factory grooves without forcing or pinching.

Made from NBR rubber, it handles hydraulic oil, moderate heat, and the pressure spikes these machines see daily. No swelling, no hardening after install—just a clean, dependable seal.

Packaged individually with the XCMG logo and part number on the sleeve. No guessing, no aftermarket substitutes. Pull the old one, match it up, and it drops right in.

Keep a couple in the truck box. When you’re in the middle of a job and a hard line starts seeping, this is the exact ring that gets you back running without chasing parts.
