Technical Products Co – PLUG WINTERIZING 3/4 inch PIPE #4

The freeze plugs are designed to seal your plumbing lines against freezing. The plugs feature stainless steel washers with brass slotted screws. An easy-to-turn reinforced handle (Easy Grip shown) helps to provide a tighter seal than ordinary plugs. Simply insert the plug into the pipe and turn the handle. This motion causes the plug to expand in the pipe creating a tight fit that will keep water out of the plumbing.
