Why are gas bottles reverse thread?

These gas fittings are made for gases such as flammable propane and hazardous phosgene. These fittings feature a reverse thread, which means that the threads are cut in reverse from all other fittings to prevent gas lines being connected to water lines, air lines, or vent lines.



The same goes for propane tanks. Why are they threaded backwards in the tank?

Reverse threads on a propane tank connection can make it difficult to remove the regulator from the tank valve. The wrong way to turn the valve nut will cause it to tighten and jamm the threads. Reverse threads are used for connections in propane tanks.

You may also be wondering what to do with old gas bottles. Gas bottles can be recycled at some local recycling centers. You should check with the staff at the recycling center where you want to leave the bottles so that they can be safely stored before being re-used.

Moreover, why is the reverse of plumbing threads?

The U.S. uses right-hand tapered thread for its supply lines. This thread is similar to water pipes. To prevent accidental connections to other purposes, fittings used to connect gas couplings such as propane and acetylene tanks use the reverse threads.
