Curious about the meaning of acronym on this line wrench. Wrench stamped (10 JOBL) Googling JOBL brings up flare wrench info but doesn't define acronym. If you can define this please use little words as you might be dealing with the guy who put 950 wrenchs on a spread sheet and then hit delete column instead of delete row. These two keys are noooooot interchangeable. May have asked this before but don't find any pics of this wrench in my files.

It appears to be a Japan industrial pipe fitting standard. J identifies a group of adaptors with hex line fittings, OB is a class for adaptors for different sized threads on each side, and L is a specific type. 10 is a size.

Size 10 couples a 1-14UNF fitting to a 7/8-14UNF fitting..

This is a little bit of a guess tho.....

How big is the wrench?

Your spreadsheet should have an undo feature?

Rusty,
Why would a Japanese wrench have english characters stamped in it? With the location of the lettering, I think that the tool was made to order for an assembly line. A standard flare wrench that was cut off and riveted to a shop made handle. This is pretty common practice in the auto industry. It looks to be about the size of a 22mm nut so the 10 would maybe be the size of the tubing? How about Job L? Many auto prototype projects had letters for names.

 Wrench is 18mm across points. Could be 10mm tubing would be about right size. Maybe my acronym is not an acronym after all. Just noticed there is (40) on handle on opposite side. Looks like an engraver was used. Maybe a section # on assembly line?

I've never seen a Japanese wrench that didn't.

When I think about it, most Japanese wrench companies even have English names!

If anyone has a picture of a Japanese wrench with Japanese characters on it I would like to see it.  Never seen one.
