Description
Horizon Size 00 Winterizing Plug, 1/2 in Pipe
Tapered expansion plug for off-season plumbing seal-up.
Genuine Horizon 00 tapered winterizing plug, sized for 1/2 in Pipe. Push-in expansion design seals open plumbing ends so freeze damage cannot crack a return line or fitting over winter. Reusable plastic plug with a captive wing nut, drives the rubber gasket against the inside diameter for a positive seal. Outer diameter is ~0.456 in, the standard Technical Products / Anderson plug-size 00 cross-reference.
