Introducing the dual head. This version can be used to apply flux to both 15mm and 22mm copper pipe. 1 x 15mm/22mm bristle head 1 x removable brush and 1 x e75g tube of flux paste, enough for approx 500 joints. 1. First use, twist the base of the manageable click system to the dotted feed line. For use there after a couple of clicks should be enough. 2. The plunger will push the flux up to the bristles. 3. Push the Fluxuator onto a pipe. 4. Twist the Fluxuator around the pipe for a full coating. 5. For hard to reach places, use the removable brush. 6. Solder the joint as normal.
