Milwaukee O-Ring — ID11 x OD16.4 x CS2.7
Model Number: 34-40-0166
The Milwaukee 34-40-0166 is a genuine OEM O-Ring with specific dimensions of 11 mm inner diameter, 16.4 mm outer diameter, and 2.7 mm cross-section for use in compatible Milwaukee tools. The O-ring is a toroidal elastomeric seal that seats in a machined groove and prevents fluid, lubricant, or air from passing across the sealed interface under compression. The explicit dimensions (ID11 x OD16.4 x CS2.7) confirm the exact geometry required for this sealing interface — substituting an O-ring of different dimensions will result in incorrect sealing. A hardened, cracked, or extruded O-ring requires replacement with the exact specified dimensions to restore the sealed interface on the tool it serves.
Using a genuine Milwaukee OEM O-ring ensures the exact 11 x 16.4 x 2.7 mm dimensions and correct elastomer specification. Always verify your catalog number before ordering to confirm this is the correct O-ring for your specific unit.
