Red Devil sausage caulk gun replacement nozzles are perfect for a variety of projects and can be used and reused in any standard-sized sausage gun. They're made of high-quality HDPE (High-Density Polyethylene) plastic material and are durable, washable, and reusable. The attachable nozzle can be trimmed as desired to control the width and speed at which the product is dispensed. Just trim the tip of the nozzle to your desired bead size and insert the trimmed nozzle into the front of any standard 20 oz. sausage gun.
