If a gas product is converted to the other type of gas, a sticker is placed near the original serial tag and rating plate to indicate the gas type change.Can you use compression fittings on copper gas lines?
Copper Fuel Gas Fittings. For copper natural gas systems joined with flared tube connections, flared brass fittings of a single 45 o flare type are used, Figure 15. Compression fittings in a gas piping system are not permitted unless allowed by the authority having jurisdiction.Why should you apply refrigerant oil to the flare cone before making a flare?
Why should you apply refrigerant oil to the flare cone before making a flare? to prevent binding and create a smoother flare surface with a bit on the back of the flare as well to allow the nut to slide easily.Why do you flare copper tubing?
During assembly, the flared end of the copper pipe is secured to the tapered fitting by the flare nut. It allows for leak-tight and pressure resistant seal. The two parts of flare fitting, the flare nut and the actual flare fitting, should fit easily together.Can you double flare copper tubing?
If you use copper tubing with a flare fitting, standard flare will be perfectly acceptable. Propane pressure is only slight (around 10" water, or 0.36 psi). Double flare is used for high pressure applications, such as hydraulic lines and automotive brake lines.
