Milwaukee Rubber Boot
Model Number: 45-12-0027
The Milwaukee 45-12-0027 Rubber Boot is a genuine OEM replacement part designed for use on the Milwaukee 2821-20 M18 FUEL SAWZALL Reciprocating Saw and the 2822-20 M18 FUEL SAWZALL Reciprocating Saw with ONE-KEY (both serial code L37A). The rubber boot is the protective rubber sealing component installed on the SAWZALL gearcase that protects internal components, contains grease within the gearcase, and keeps debris, dust, and contaminants out of the gear train and bearings during heavy demolition, remodel, plumbing, electrical, and metal cutting work. Manufactured to Milwaukee's exact factory tolerances and rubber compound specifications, this OEM boot restores correct sealing, proper component fitment, and full debris exclusion after wear, hardening, cracking, tearing, or chemical degradation of the original boot.
SAWZALL reciprocating saws are exposed to one of the harshest service environments in the entire power tool catalog because of the constant high-frequency reciprocating motion, the wide range of cutting media (wood, metal, drywall, plaster, ABS, masonry, nail-embedded lumber), the heavy debris loads kicked back into the front of the tool during demolition work, and the temperature extremes encountered on the jobsite. As the rubber boot ages, it hardens, loses elasticity, develops cracks, and eventually fails to seal correctly. Once the boot fails, grease begins to escape from the gearcase and abrasive jobsite debris begins to enter, accelerating wear on bearings, bushings, gears, and the spindle assembly and ultimately leading to expensive internal repairs. Replacing the rubber boot at the first sign of cracking, hardening, or visible damage is one of the highest-value preventive maintenance steps an owner can take on a 2821-20 or 2822-20 SAWZALL. Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee 2821-20 or 2822-20 service parts diagram before ordering, since Milwaukee occasionally implements running production changes that affect part compatibility within the same catalog number. Verify by serial number using Milwaukee's online parts lookup before ordering to confirm correct fitment.
