Milwaukee 34-40-1050 O Ring

**Milwaukee parts change not only by model# but also by serial number. Milwaukee’s site lets youlook up your tool’s parts diagram.Milwaukee O-RingModel Number: 34-40-1050The Milwaukee 34-40-1050 is a genuine OEM O-Ring for use in compatible Milwaukee tools. O-rings are precision-molded elastomeric sealing rings with a circular cross-section that seat into a machined groove and are compressed between two mating surfaces creating a reliable static or dynamic seal that prevents fluid, air, or lubricant from passing the sealed interface. They are used throughout Milwaukee tool assemblies in applications such as gearcase oil seals, pump seals, valve seats, cylinder seals, and hydraulic/pneumatic circuit seals. An O-ring that has hardened, cracked, been cut, or has permanently compressed beyond its elastic recovery can no longer form a proper seal and requires replacement to restore leakproof performance at the sealed interface.Using a genuine Milwaukee OEM O-ring ensures the correct inner diameter, cross-section diameter, and elastomer compound for the groove and fluid compatibility requirements of the interface it seals. Non-OEM O-rings may not match the original dimensional tolerances or material compound, leading to inadequate sealing or chemical incompatibility. 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.FeaturesGenuine Milwaukee OEM O-ring for compatible Milwaukee toolsCircular cross-section elastomeric ring seals between two mating surfaces under compressionUsed in gearcase seals, pump seals, valve seats, and hydraulic/pneumatic circuit sealsReplacement restores leakproof sealing when original O-ring hardens, cracks, or permanently compressesVerify catalog number and serial number on Milwaukee’s website before orderingSpecificationsType: O-RingMaterial: Elastomeric Rubber CompoundApplication: Static and Dynamic Fluid, Air, and Lubricant SealingCompatibility: Always verify part compatibility using your tool’s model and serial number before orderingIncludes(1) Milwaukee 34-40-1050 O-Ring
