Milwaukee 12V Caulk Gun Kit, Sub-Compact Sealant Gun with 310ml Holder

The 310 ml cartridge holder is sized for standard large sealant cartridges, enabling you to load a full cartridge and complete longer runs without frequent reloading, which improves efficiency and consistency of bead application.

The sub-compact design makes the tool shorter and lighter, allowing easier access in cramped spaces like behind sinks, along shower enclosures, and around cabinetry. This reduces fatigue and improves control for precise bead placement.

Steps: (1) Remove the old cartridge, (2) insert a new 310 ml cartridge into the holder, (3) attach the nozzle or tip if needed, (4) retract the plunger and lock it, (5) press the trigger to start dispensing and guide the bead smoothly, (6) stop pressing and release to halt flow before ending a bead.

Wear eye protection and gloves, keep hands away from the nozzle during dispensing, ensure the battery is properly attached, work in a well-ventilated area, and store the tool away from children when not in use. Clean the nozzle after use to prevent sealant from curing inside.

The tool operates on Milwaukee’s M12 12V system and uses a 2Ah battery. It’s designed for efficient, portable operation with the flexibility of battery-powered use for extended projects, depending on sealant viscosity and bead size.

The 201B model is typically the battery-powered kit version, offering immediate use with a battery and charger, whereas the 201A is often the bare tool without battery/charger. Availability and contents may vary by listing, so check the specific product pages for details.

The 201C variant usually represents a different kit configuration or accessory set. The 201B focuses on the core sub-compact caulk gun with a 310 ml cartridge holder, while the 201C may offer different inclusions. Compare contents and battery compatibility on the respective product pages.

It's suitable for standard sealing materials like acrylic latex, silicone, and polyurethane sealants, especially those packaged in 310 ml cartridges. Check your sealant’s viscosity and the gun’s plunger speed to maintain a smooth bead.

Keep the nozzle clean after use, wipe away excess sealant from the plunger rod, charge and store the battery in a cool, dry place, and periodically inspect the trigger mechanism and seals for smooth operation. Avoid exposing the tool to moisture or extreme temperatures when not in use.

Look for 310 ml cartridges and compatible nozzles/tips, additional M12 batteries, and chargers, plus any Milwaukee M12 kit bundles that include the sub-compact caulk gun. These additions help you deploy the tool effectively across multiple projects.

The cordless design reduces hand strain, provides consistent bead pressure, enables one-handed operation in tight spaces, and supports longer runs between reloads due to the cartridge holder. This can lead to faster completion times and a more professional finish on complex jobs.
