While you're purchasing your new commercial gas equipment, don't forget the hose! These heavy duty hoses connect right up to your gas lines. They are generally available in 3 feet and 4 feet. The valve sizes are generally 1/2" and 3/4". You can be confident in the quality of our hoses as we stock them from reputable vendors like Dormont and Choice Products. Remember that it's usually a good idea when designing your kitchen to have the gas valves placed no more than 3 feet away from where you plan to place your gas equipment.
