Rubber Winter Expansion Plug for Winterizing Pools. 

Get ready for winter and keep 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 and are available in 8 standard sizes to fit pipe from 3/4” to 2”.

Our Easy-Grip, No-Slip (EGNS)TM 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.

TESTING: Winterizing Plugs are ideal for testing applications. Once installed the system can be pres- surized and tested for leaks.
