Milwaukee 20 oz. Aluminum Barrel
Model Number: 45-76-0900
The Milwaukee 45-76-0900 is a genuine OEM 20 oz. Aluminum Barrel for use in compatible Milwaukee M18 Cordless Caulk and Adhesive Guns. The aluminum barrel is the rigid metal tube that holds the 20 oz. sausage-pack adhesive or caulk cartridge — providing the structural barrel housing that the plunger rod advances through to dispense material. The aluminum construction provides superior strength and durability compared to plastic barrels, resisting deformation under the high dispensing force generated by the M18 caulk gun motor during thick adhesive application. A cracked, dented, or stripped aluminum barrel that cannot maintain a seal with the gun body or accept a cartridge correctly requires replacement to restore full caulk and adhesive gun performance.
Using a genuine Milwaukee OEM aluminum barrel ensures the correct bore diameter, thread specification, and thread engagement for the M18 Caulk and Adhesive Gun it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct barrel for your specific unit.
