Technical Products SP201 is a winter plug designed to seal 1/2-inch pool plumbing lines by expanding to form a watertight barrier. The plug uses high-quality rubber with heavy-duty nylon and stainless steel components and installs with a large plastic wing-nut for tool-free tightening. It is reusable and suitable for winterizing, pressure testing, and leak detection on skimmers, main drains, and cleaner lines.
