Steel, copper, brass: The most common gas piping is black steel. Galvanized steel, copper, brass or CSST (Corrugated Stainless Steel Tubing) also can be used in some areas, but some utilities specifically prohibit the use of copper. Galvanized steel is used in some areas as well.Click to see full answer. Then, can compression fittings be used on gas lines?Compression fittings in a gas piping system are not permitted unless allowed by the authority having jurisdiction. All tube fittings for natural gas installations are rated at more than 125 psig, but should not be used at pressures beyond those allowed by local codes.Subsequently, question is, can you use brass fittings on iron pipe? Less exposure between the two metals will lessen corrosion probability. For example, use more brass for piping connections compared to the iron. Less iron exposure to the brass will minimize electrolysis. Regarding this, what do you use on gas pipe threads? On the stove end, use another flare-to-pipe-thread fitting. Remember to apply pipe thread compound or gas-rated Teflon tape to the threads on threaded connections before assembling them. Flare joints rely on a tight fit to seal and don’t require additional sealant.Can you use Teflon tape on gas lines?Teflon tape for gas fittings, also known as gas-rated Teflon tape, is yellow in color and clearly states it is for gas lines and connections. The tape works on all gas line types, including butane, propane and natural gas lines. The tape cuts easily with a utility knife or scissors.
