Reply To: Union in a natural gas line

YES IT IS OKAY TO USE UNION ON NATURE GAS SYSTEM, BUT IT NEEDS TO BE ACCESSIBLE. WHICH MEANS IT CAN NOT BE IN A WALL. IF YOUR PROBLEM IS IN A WALL YOU WILL NEED TO USE A LEFT RIGHT NIPPLE .. THIS WILL BE A COUPLING AND NIPPLE THAT WHEN YOU INSTALL IT YOU THIGHTEN CLOCK WISE AND IT WILL THIGHTEN BOTH ENDS.. GOOD LUCK YOUR FRIEND THE PIPEXPERT…
