As a professional in the field of plumbing and gas fitting, I can provide you with a comprehensive answer regarding the use of Teflon tape on gas fittings.
Teflon tape, also known as PTFE (Polytetrafluoroethylene) tape, is commonly used in plumbing to create a leak-proof seal on threaded pipe connections. It is a thin layer of plastic that is wrapped around the threads of a pipe or fitting to prevent leaks when the connection is tightened. However, when it comes to gas fittings, the use of Teflon tape can be a bit more complex and requires a careful consideration of safety standards and the specific type of gas fitting involved.
Firstly, it is important to understand that gas fittings are subject to strict regulations and safety standards due to the highly flammable nature of gas. Any connection that is not properly sealed can lead to gas leaks, which pose a significant risk of fire or explosion. Therefore, the choice of sealant is crucial.
When assembling gas fittings, especially those that are threaded, it is often recommended to use a pipe thread compound or a gas-rated Teflon tape. The reason for this is that these materials are specifically designed to withstand the pressures and temperatures associated with gas lines. A regular Teflon tape may not have the necessary specifications to ensure a safe and secure seal under these conditions.
The reference material you provided suggests using a flare-to-pipe-thread fitting on the stove end and applying a pipe thread compound or gas-rated Teflon tape to the threads before assembling. Flare joints, on the other hand, rely on a tight fit to seal and do not typically require additional sealant. This distinction is important because flare fittings and threaded fittings have different sealing mechanisms.
Flare fittings create a seal through the compression of a flare nut against the flare of the pipe, which is then tightened onto a male pipe or fitting. This type of connection does not require a sealant because the metal-to-metal contact is what provides the seal. However, if there is any doubt about the integrity of the flare joint, it is always safer to consult with a professional or refer to the manufacturer's guidelines.
Threaded gas fittings, on the other hand, often require a sealant to ensure a leak-proof connection. This is where a pipe thread compound or a gas-rated Teflon tape comes into play. The compound or tape fills the gaps and threads, creating a barrier that prevents gas from escaping.
It is worth noting that not all Teflon tapes are created equal. Some tapes are specifically formulated for gas applications and meet the stringent requirements set by gas safety standards. These tapes are designed to withstand the corrosive properties of gas and maintain their sealing properties over time.
In conclusion, while Teflon tape can be used on gas fittings, it is essential to use the correct type of tape and follow the proper application procedures. Always refer to the manufacturer's instructions and local regulations to ensure that your gas fittings are installed safely and correctly. If you are unsure about any aspect of gas fitting, it is best to consult with a licensed professional to avoid any potential safety hazards.

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.
