Milwaukee O-Ring
Model Number: 34-40-1511
The Milwaukee 34-40-1511 is a genuine OEM O-Ring for use in compatible Milwaukee tools. The O-ring is a toroidal elastomeric seal that seats in a machined groove and provides a dynamic or static seal between two mating components — compressing under assembly load to fill the groove cross-section and prevent fluid, lubricant, or air from passing across the sealed interface. O-rings in Milwaukee tools are used at rotary shaft seals, piston interfaces, fluid port connections, and housing mating grooves where a reliable, compact seal is required. O-rings are a consumable service item that harden, crack, and lose elasticity over time and under exposure to heat, lubricants, and mechanical cycling. A hardened, cracked, or extruded O-ring that can no longer maintain its sealing cross-section requires replacement to restore the sealed interface. Always order by exact catalog number — O-ring dimensions and elastomer compound are specific to the interface they seal.
Using a genuine Milwaukee OEM O-ring ensures the correct diameter, cross-section, and elastomer for the sealing interface it serves. 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.
