Technical Products 13 3/4 Winter Plug, w/ White Wing Nut, 3″ Sched 40 Fitting, Winterizing Plug SP21375
Seal the line before the freeze finds it.
Technical Products 13 3/4 Winter Plug, w/ White Wing Nut, 3″ Sched 40 Fitting, part SP21375 is a rubber expansion winterizing plug, stocked under SKU PST-SP21375. The number and size in the part name tell you exactly what it seals, so match it to the pipe or fitting you are closing before you order. Slide the plug into the opening and tighten the nut: the rubber body squeezes down, swells against the wall, and locks in place. Sealing returns and blown out lines is what keeps water from working its way back into plumbing and splitting a pipe when the temperature drops.
