The Flo-Control Nozzle (99 cents) is designed to stop overflow from silicones, adhesives and gap fillers applied with a caulking gun. The nozzle’s special chamber not only stops the contents from drying and blocking a container’s application tip; it also draws the material back through the nozzle and into the container when you’re finished, minimizing waste. The Flo-Control Nozzle screws into place and fits most caulking guns. Nevleck Pty Ltd., www.bostik.com.au
