XCMG Spare Parts SEAL RING79*82*9.5 803300616

This is an OEM-grade seal ring, factory number 803300616, precision-engineered for XCMG heavy machinery. It fits a critical 79mm shaft with an 82mm housing and a 9.5mm cross-section—tight tolerances that matter when you're rebuilding a hydraulic cylinder or final drive.

Made from high-grade nitrile rubber, this seal holds up against hot hydraulic oil, pressure spikes, and the grit of a jobsite. It’s not a universal generic; it’s cut to the exact spec XCMG uses on their wheel loaders, excavators, and motor graders.

You’ll notice the lip design on this one. It’s molded for a firm interference fit, which means no twisting during installation and a clean seal edge that won’t score the housing bore. No leaks, no premature wear.

We keep these in stock because they’re a routine replacement item—especially on boom cylinders and swing drives. If you’re pulling a cylinder apart, this is the ring you want in the kit.

Comes in the standard XCMG parts bag with the laser-etched part number for traceability. Cross it with 803300616 before installing, and you’re good to go.
