Winterizing Freeze Protection Return Rubber Plugs
The freeze protection 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.
