There are many hose reels on the market that don't leak. You can find them made of different materials such as plastic or metal. Some have a rubber washer that creates a seal between the hose and the reel, while others have a ball bearing that stops the hose from leaking. If leak-proof is high on your priority list, we suggest the ELEY Hose Reel Cart with Wheels, as it has the best no leak record over other models.
