These self-coiling hoses have a 3/8" inside diameter that provide good water flow. You can water anything up to 25' or 50' away from the faucet, and when you return to the faucet, the hose springs back into a neat coil about 17" or 30" in length respectively.
The hoses come with 3/4" brass couplings that fit standard garden faucets and any hose-end accessories you might want to use with them. Hose material is opaque to eliminate algae build-up. Not for use with hot water.
