Our rubber expansion plugs allow you to plug your plumbing lines to keep the water out during the winter season. Protect your pool and your equipment! These rubber plugs come in an array of sizes and each plug’s diameter can be adjusted when turning the wing nut attached. These pool plugs can be used on pool returns, pool cleaner lines and skimmers to protect the pipes from water which will freeze over the winter and damage, if not break, your equipment.
Remember to check your pool plugs every year before winterizing to ensure that deterioration has not occurred!
