The #9.5 pool plug forms a secure seal in 1½" PVC fittings, making it an essential tool for winterizing your pool. After draining and blowing out the lines, insert the plug to keep water out and help prevent freeze damage to in-ground plumbing.
Constructed from durable rubber with heavy-duty nylon and stainless steel components, it resists corrosion and delivers long-lasting performance. The easy-turn wing nut tightens smoothly and provides up to 50% more sealing power than standard plugs.
