Milwaukee Cartridge Mounting Cap
Model Number: 42-52-0440
The Milwaukee 42-52-0440 is a genuine OEM Cartridge Mounting Cap for compatible Milwaukee caulk and adhesive guns — the end cap component that retains and positions the caulk or adhesive cartridge in the gun barrel for correct dispensing alignment and secure cartridge engagement during operation. The mounting cap holds the cartridge's nozzle end in the correct position relative to the gun's output path so the plunger can advance through the cartridge for consistent, controlled material dispensing throughout the cartridge's full volume. When the mounting cap cracks, deforms, or loses its retention geometry from physical damage or wear, the cartridge may shift position in the gun during dispensing — producing off-axis material flow, inconsistent bead size, or cartridge rotation that interrupts controlled application.
Using a genuine Milwaukee OEM mounting cap ensures the correct cartridge bore diameter, retention geometry, and material for the specific Milwaukee caulk gun model and cartridge size it is designed for — a cap with incorrect bore dimensions will not properly center or retain the cartridge for accurate dispensing. Always verify your specific Milwaukee caulk gun model number and serial number at milwaukeetool.com before ordering cartridge mounting cap service components, as specifications vary between Milwaukee caulk and adhesive gun models and cartridge size configurations.
