Caulking gun HOGERT HT4R407 with steel and aluminium handle, 310 ml capacity

Caulking gun HOGERT HT4R407 with steel and aluminium handle, 310 ml capacity is a manual applicator designed to work with standard 310 ml cartridges of sealants and adhesives. The tool combines a steel frame with an aluminium handle for a balance of durability and reduced weight. It provides steady extrusion and precise bead control for sealing joints, installing windows, bathroom fixtures, and general construction or DIY sealing tasks.

Advantages

The steel frame ensures structural rigidity during continuous use while the aluminium handle reduces overall weight and improves handling. The ergonomic handle shape provides comfortable manual control and consistent pressure for even bead flow. The gun supports standard cartridges and offers smooth rod movement to minimise drips and interruptions. Its straightforward, mechanical design makes it low-maintenance and reliable for repeated sealing and adhesive applications.

Suitable for

• Applying silicone, acrylic and polyurethane sealants in joints and gaps
• Sealing around windows, doors and frames
• Bathroom and kitchen sealant application around baths, sinks and countertops
• General construction and renovation adhesive tasks
• DIY projects requiring controlled bead placement

Key specifications

• Cartridge capacity: 310 ml
• Frame material: steel
• Handle material: aluminium
• Feed mechanism: manual ratchet/rod type for controlled extrusion
• Compatible with standard 310 ml sealant and adhesive cartridges
• Design: open-frame for easy cartridge loading and cleaning

How to use

Prepare the surface by cleaning and drying the area to be sealed. Cut the cartridge nozzle to the desired bead size and puncture the inner seal if present. Insert the cartridge into the caulking gun, ensuring it sits securely in the frame. Advance the rod until it contacts the cartridge base, then squeeze the aluminium handle to extrude the sealant. Maintain steady pressure and steady movement along the joint for an even bead. Release the pressure mechanism between passes if required to reduce residual flow. After use, retract the rod, remove the cartridge, and wipe any excess sealant from the gun.

Usage recommendations

Use cartridges appropriate for the materials and environment (e.g., silicone for wet areas, polyurethane for stronger adhesion). Store the gun in a dry place and clean exposed surfaces after each use to prevent buildup. For long jobs, choose a nozzle size that matches the joint width and consider using a steady, continuous motion for uniform beads.
