14mm Male Ground Joint Forming Tool - Aluminum Handle - Griffin Glass Tools

Make your own male 10-1 joints quickly and easily. First, establish where the back should of your joint will be and gather or thicken that area slightly, pull your tubing to a slight taper then get the whole thing hot and blow into the male forming tool. You’ll end up with a perfect taper every time. Make colored joints or joints from lined tubing in just a couple of steps. We chose brass instead of graphite for this product for longevity and consistency of the formed joint shape after multiple uses.
