Milwaukee Plunger and Screw for M12 and M18 10 oz. Caulk and Adhesive Guns
Model Number: 44-70-0330
The Milwaukee 44-70-0330 is a genuine OEM Plunger and Screw for Milwaukee M12 and M18 cordless 10 oz. caulk and adhesive guns including the 2441-20, 2640-20, and 2641-059. The plunger is the plastic piston that fits snugly inside the gun barrel between the hex nut and cartridge holder — it is the component that the drive rod pushes forward to apply pressure to the back of the 10 oz. cartridge and force caulk or adhesive out through the nozzle. The plunger is a wear and consumable item that can crack, deform, or get contaminated from cartridge blowouts and material buildup during normal use, particularly when caulk tubes rupture inside the barrel. Replacing the plunger restores correct dispensing pressure and a proper barrel seal on the 10 oz. cartridge. A Phillips head mounting screw is included. A screwdriver may be needed for installation.
Using a genuine Milwaukee OEM plunger ensures the correct barrel diameter and piston geometry for the compatible 10 oz. caulk and adhesive gun models. Always verify your catalog number and serial number before ordering to confirm this is the correct plunger for your specific unit.
