XCMG Spare Parts O RING 90X3.1 803183345

This genuine XCMG replacement seal is a straight-forward O-ring, but it is a critical component for maintaining hydraulic integrity on your machine. The item code 803183345 is the factory identifier, so matching this number exactly ensures you are getting the correct part specified for your equipment's assembly .

The dimensions are metric and standard for this application: 90mm internal diameter with a 3.1mm cross-section. This specific thickness gives it the durability to handle moderate hydraulic pressures without extruding, while the 90mm ID ensures a snug fit on the mating gland .

You are looking at a vulcanized rubber component, manufactured to resist petroleum-based oils and common hydraulic fluids found in loaders and excavators. Unlike generic hardware store O-rings, this one is formulated to hold its durometer (hardness) even when the machine heats up during a long shift .

We recommend inspecting the old seal during disassembly; often, a flattened or cracked O-ring like this is the culprit behind a slow leak. Replacing it during routine maintenance is cheap insurance compared to the cost of contamination or fluid loss .

This part is inventoried specifically for serviceability on XCMG heavy machinery. Whether it is for a hydraulic cylinder block, a pump cover, or a valve body, using the factory-spec 90X3.1 seal ensures the system stays sealed and free from debris ingress .
