The 6 Best 1 inch Boat Plugs (2023 reviews)

This boat plug is well made and reasonably priced. It is great as a replacement plug for the kids water table. It is made of a pliable rubber that expands or contracts depending on how much you twist the handle so it's form fitting. The plug expands as it gets twisted in. The plug is inserted and the handle screws in to tighten the connection in the plug hole. It should go in kind of snug and then the small amount of expansion makes a tight seal.

This is a 1 " bilge plug for a 1 " hole, which will expand when you crank on the handle. It’s threaded straight thru.
