XCMG Spare Parts O RING 254X5.3 801139266

This is a genuine XCMG replacement O-Ring, designed for a tight, leak-proof seal in hydraulic systems. It is a standard metric size, measuring 254mm in inner diameter with a 5.3mm cross-section. We typically see these used in heavy-duty cylinders and pump assemblies.

The rubber compound feels firm but flexible, holding its shape to withstand high pressure without deforming. It’s resistant to mineral oils and hydraulic fluids, which is critical for long service life on site. If you are rebuilding a cylinder, always swap out the old o-rings for fresh ones like this.

You can verify it by the part number 801139266 cast on the packaging. It matches the original specs for several XCMG motor graders and large excavator models. We keep these in stock because they are a common wear item that needs replacing during regular maintenance.

When fitting, make sure the groove is clean and free of debris. This particular size seats correctly the first time if installed carefully. It is a small component, but it prevents major leaks that lead to downtime and fluid loss on the job.

This listing is for one brand new, genuine XCMG part. It comes in the official sealed bag, ensuring it hasn't been exposed to dirt or damage. Reliable seal, correct fit—just what the machine needs.
