This handy rubber drain plug fits most air cooler drain hole models to prevent leaks and messes. Made of durable rubber, it creates a water-tight seal to block drainage when the cooler is not in use. Easy to install and remove, simply push it into the drain opening until it locks securely. Great for seasonal storage or transport, it keeps residual water contained inside instead of spilling out. Its compact design makes it convenient to store when not installed. Help keep your cooler and surrounding area dry between uses with this affordable plug - just pull it out before the next cooling season begins.
