Gas powered equipment requires special high quality hoses to connect the gas supply to the equipment in order to operate efficiently and safely. Unique tubing is required and any operator must be able to trust that their tubing will hold under the normal pressures of gas fuel. You must consider the diameter of the gas inlet on the equipment you are hooking up to. It is also handy to use a quick disconnect hose so that you don't have to cut off the main gas valve when disconnecting the oven. If you don't see the diameter hose you require call us, we'll find you exactly what you need.
