Tube pipe insulation may be used on domestic cold and hot water pipes. Pipe insulation will help to reduce heat loss by up to 80 percent through hot water pipes and will stop sweating on cold water pipes. Pipe insulation can also help reduce plumbing noise. It is pre-slit for easy installation (simply snapping onto the pipe), and may be trimmed with a utility knife. One package includes four 3ft long pieces, with this 5/8 inch ID (inside diameter) tube suitable for use on 1/2" copper tubing, 1/4" PVC pipe, and 1/4" iron pipe.
