Description
Technical Products 9 3/4 Deep Flange Plug, 1 1/2″ Return Without Internal Seat, Winterizing Plug SP20975FD
Seal the line before the freeze finds it.
Technical Products 9 3/4 Deep Flange Plug, 1 1/2″ Return Without Internal Seat, part SP20975FD is a rubber expansion winterizing plug, stocked under SKU PST-SP20975FD. 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.
