Griffin Glass Tools - 19mm Male Brass Joint Shaper - Aluminum Handle

Make your own male joints quickly and easily. First, establish where the back of your joint will be and gather and thicken that area slightly. Pull your tubing to a slight taper, then get the whole thing hot and blow into the male forming tool and you'll end up with a perfect taper every time. Make colored joints from lined tubing in just a couple of steps. We chose brass insead of graphite for this product for longevity and consistency of the formed joint shape after multiple uses. This product is 19mm and has a brass head and aluminum handle.
