something you don't see every day, left-handed pipe tap
We were going through some cabinets in my machine shop today, cleaning and organizing.
One of the guys showed me something I have never seen before, a 3/4" LEFT HANDED national pipe thread tap. Left hand threaded pipe? That's a new one on me. Anyone care to explain that one? the best I could come up with would be to keep from mixing up fuel and oxygen like on a torch but those are usually machine threads, not pipe threads. |

Need a left handed pipe wrench to go with it
 Seriously though, interesting find. Could be worth something.

Pipe coupler unions are not allowed under house floors for natural gas. So, we use left-rights to join when a splice is necessary. You can buy a LR nipple to do the job at almost any supply, but to have the die would be cool.
no go:  Oh, you have a tap. Oh well, it could be useful I suppose. |
