Milwaukee O-Ring Hub
Model Number: 34-40-1380
The Milwaukee 34-40-1380 is a genuine OEM O-Ring Hub for use in compatible Milwaukee tools. This O-ring is specifically installed at the hub interface — sealing between a rotating hub assembly and its mating housing bore to prevent lubricant from escaping the gearcase or bearing housing at the hub location, while excluding external contaminants from entering. Hub O-rings must accommodate slight relative movement at the hub-to-housing interface while maintaining their sealing lip or face contact. An O-ring at the hub that has hardened, cracked, or extruded out of its groove allowing lubricant leakage at the hub interface requires replacement to restore a sealed, leak-free gearcase assembly.
Using a genuine Milwaukee OEM O-ring hub ensures the correct inner diameter, cross-section diameter, and elastomer compound for the hub groove and interface it seals. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct O-ring for your specific unit.
