Anderson Manufacturing O55 Standard Open Winterizing Plug for 2 inch Pipe, 1-7/8 inch
Hollow stem rubber plug for blowing out and winterizing 2 inch pool lines.
The Anderson Manufacturing O55 Standard Open Plug (SKU PST-ANDO55) is a 1-7/8 inch straight-sided rubber test plug sized for 2 inch pool plumbing. The hollow stem and combination 1/8 inch NPT thread plus 3/8 inch hose barb top let you pump compressed air through the plug to clear and pressurize return lines, skimmers, and main drains during winterization. Tighten the large corrosion-resistant wingnut to expand the rubber against the pipe wall, blow the line clear, then leave it in place all winter to keep water out.
