A tapered tube plug is selected so that the inside diameter of the

heat exchanger/boiler tube is approximately matches the mid-range of

the tube plug's taper. The tapered tube plug is inserted into the heat exchanger/boiler tube and driven in with a hammer to seal off the tube. One tube plug is required for each end of a leaking heat exchanger/boiler tube.
