Marketing InformationKeep pipes from freezing and bursting. Our winterizing plugs are made with soft rubber which allows for maximum expansion. They provide a tight seal, even during expansion and contraction due to severe temperatures. They feature a tighter contour to make installation quick and easy. Available in 8 standard sizes to fit pipe from 3/4" to 2". The Easy-Grip, No-Slip (EGNS)™ knob has been specifically designed to make hand tightening easier and less painful on the fingers. The larger grip also accepts a 1" socket making installation and removal a snap.
