Hi this item have two pices ? one right hand thread and lelf hand thread ?

Right hand is for the green oxygen hose and the left hand coupler is for the red acetylene hose.

Hi this item fit with Uniweld 71 Welding Handle ?

Yes from 1/4 hose fittings up to standard hose fittings

will this fit tee uniweld wh550 torch?

The Uiweld WH 550 torch has type “A” connections, which the small end of this adaptor has. If you’ll be connecting it to a type “B” hose, the most common size, then it should work fine.

Have b hose and a torch. "3/8" - 24 (a) female x 9/16" - 18 (b) male" it should be ok but not by ""a" size hose to "b" size torch"? seller fix this

Correct, the title is accurate, but the fine print description under the picture is incorrect. This connects an A torch with smaller fittings (prestoweld for example) to a standard large B sized hose (hose for Victor products)
