Description
Technical Products #13-3/4 Winter Plug with White Nylon Wing Nut, 3" Sch 40 Fitting, Pool Closing Plug SP21375
Numbered to the opening it seals.
Technical Products #13-3/4 winter plug (SP21375) is a rubber expansion plug for winterizing pool plumbing. It fits 3" Sch 40 fitting. Push it into the opening and turn the wing nut: the rubber compresses, swells against the wall and holds the seal. Technical Products builds its plugs from rubber, stainless steel and heavy duty nylon, so nothing in the plug corrodes sitting in a line all winter.

Good to Know
Pipe, fitting or tube: which one do I have?
A pipe size means the plug goes straight into the open end of the pipe itself. A fitting is the socket or threaded opening a pipe slides into, which is wider than the pipe of the same nominal size, so it takes a bigger plug. Tube sizes are for thin-wall tubing. If you are not sure, measure the inside of the opening and compare it with the rated diameter in the specs.
Will a winter plug stop freeze damage by itself?
No. A plug keeps water out of a line you have already cleared. Blow the line out and lower the water below the returns first, then set the plug. Snug the wing nut by hand until the rubber grips; a plug cranked tight all winter is harder to back off in spring.
