Milwaukee O-Ring
Model Number: 34-40-0126
The Milwaukee 34-40-0126 is a genuine OEM O-Ring for use in compatible Milwaukee tools and attachments. An O-ring is a precision elastomer ring that seats in a machined groove to seal a joint against the ingress of debris, moisture, or fluid, or to cushion and retain components where two parts meet. On the hedge trimmer attachment it serves the attachment's coupling and drive interface, helping keep the connection sealed and seated in use. O-rings are wear items that harden, flatten, tear, or take a set over time, and a worn or missing O-ring can allow leakage, play, or contamination at the joint. Milwaukee uses distinct part numbers to differentiate O-rings by inside diameter, cross-section, and material, and O-rings that look nearly identical are frequently not interchangeable, so order by the exact part number shown at the correct figure position on your tool's service parts diagram rather than by visual comparison. Lightly coat the O-ring with grease before installation, as Milwaukee directs.
This O-ring is identified as the O-Ring, Figure 14, on the Milwaukee service parts lists for the 49-16-2719 M18 FUEL QUIK-LOK Hedge Trimmer Attachment, serial K52A, bulletins 54-49-2810 and 54-49-2815. The 49-16-2719 attaches to the M18 FUEL QUIK-LOK power head to run as a hedge trimmer, and this O-ring is a component of that attachment. O-rings are commonly shared across QUIK-LOK attachments, so it may serve additional attachments; confirm applicability to other attachments and the figure position for your specific unit using Milwaukee's online parts lookup. Because Milwaukee specifies service parts by serial number as well as catalog number, verify your catalog and serial number against the official Milwaukee service parts diagram before ordering, since running production changes can alter part compatibility within the same catalog number.
