Uni-Pro Heavy Duty No Drip Caulking Gun

Professional No Drip Sealant Gun for Silicone, Adhesives and 300ml–320ml Cartridges

The Uni-Pro Heavy Duty No Drip Caulking Gun is a professional applicator designed for precise dispensing of sealants, silicones and construction adhesives. Built with a strong metal frame and smooth trigger mechanism, this heavy duty sealant gun provides reliable performance for trade professionals and serious DIY users.

The integrated no-drip mechanism automatically releases pressure when the trigger is released, preventing excess sealant from continuing to flow from the nozzle. This helps reduce mess, improves bead control and minimises product waste when applying silicone or adhesives.

Designed to suit standard 300ml and 320ml cartridges, the Uni-Pro Heavy Duty Caulking Gun delivers consistent pressure for smooth and even application. The durable construction allows it to handle thicker materials such as polyurethane sealants, construction adhesives and high viscosity silicones commonly used in construction, automotive and maintenance work.

Ideal for sealing joints, bonding materials and filling gaps, this heavy duty caulking gun provides the strength and control required for professional results across a wide range of applications.
