If you have to turn the gas off at the meter then make sure you light all your pilots when your done. This includes the stove, gas fireplace units, hot water heaters, furnaces, some AC equipment, etc.
Anything with a pilot light will go out once the main gas line is shut off. After your done applying the tape, connecting your gas lines and turning the gas back on, mix a little dish soap with water in a spray bottle. Shake the bottle a little to mix the soap and water. Spray the soapy solution onto all your new gas fittings. Immediately turn off the gas and tighten the gas fittings a bit more. Then turn the gas back on and test the fitting again. If the solution is still bubbling, turn off the gas, disconnect the fitting and check the fitting for dirt, debris or damage.
Clean the fitting thoroughly, and reapply the yellow tape. Many people ask what would happen if they use the wrong tape. And the answer is a potential disaster. If you use the wrong tape on gas pipe fittings, the tape can degrade over time causing gas vapors to escape from the fitting.
Leaking gas pipes and fittings are dangerous and can cause an explosion or fire. It feels more substantial and gives you more resistance.
You can use pipe dope instead, if you wish. I always use the yellow tape on gas lines and fittings because I find it convenient. Use one or the other. If you try to use both, they will interfere with each other. Suitable tape for gas fittings or pipe has a yellowish color, like you see here. Plumber's Teflon is white in color and thinner than yellow gas -rated Teflon tape.
Leaking gas pipes and fittings are dangerous and can cause an explosion. Additionally, why is thread sealing compound not used on flare connections? Bad flare , burrs on the pipe, wrong size flare , can all cause a flare fitting to leak. The most common reason they leak is because of us overtightening them. 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.
It can sometimes be found in a silver color to match the pipes. Red tape is triple density, for pipes one-half inch to 2 inches in diameter. It is designed for pipes with larger joints, such as water distribution pipes. Keep flare end of fitting free of grease, oil and thread sealant. Use a wrench only on the hex surfaces of the fittings. What kind of Teflon tape is used for gasoline?
JRaef JRaef Can you clarify whether there's a difference in what the pipe is carrying or only if it's pipe diameter that indicates what color tape to use? Lots of questions left from your answer You can't use the tape color to determine what's in a pipe, if that's what you mean. Yellow double density tape is required for gas, but that does not preclude you from using it on water. My question wasn't about identifying the pipe's contents by the color of thread tape, but if the tape color type is determined only by pipe diameter which is sort-of how I read your post , or if the color is determined more by the contents - i.
