Inner Tube Testers
Similar to a thread protector with a hole in it, Matrix Inner Tube Testers screw into the pin end of the RC Drill Rod. Then, by running compressed air into the opposite end of the rod a leak will be revealed if there is air exiting out of the hole in the tester lid. If a leak is discovered replacement of O-rings often fixes the problem. If the leak persists, it can be concluded that the inner tube has been ruptured and it will have to be replaced or scrapped.
