I think you need a special nipple too
I got this and I also got a set that came with a nipple. I haven't installed them yet, but to have this work as a union, *I think* you also need a nipple (a short length of pipe) with right threads on one end and regular threads on the other.

Do Your Homework
I don't mean to insult anyone who has already reviewed this item, but I wonder if any of you even understood what you were purchasing? The threads are supposed to be reversed on one side - that's the whole purpose of a left/right threaded coupling and the item description clearly states that the threads are reversed on one side. This item, along with a nipple that also has threads reversed on one end, provides a place where you can take apart a part of your pipe without having to dismantle the whole system. It's an alternative to a union. I'm using it for a gas line so that I'll have one 4" nipple that can be wrenched out to re-route the last leg of the gas line when I relocate my kitchen in a year or two. This item is exactly as described and I had ZERO problems with it.

Buy this product from a different supplier
As others have noted, the right side threads work perfectly. The left side threads are misaligned, making it very difficult to attach a pipe. I do know how to use a left-right coupling, so I'm not the issue. I ordered two and ended up returning both.

Quality black iron pipe coupling!
We used 4 of these as feet for an industrial-style desk. They were easy to thread onto the pipe, are flat against the floor, and look great!

Defective
Item was cross threaded. I tried multiple nipples and could only get one end to thread. I thought initially that I may have received a standard coupling, but after many attempts I realized the item was defective. I only ordered one. I’m not sure if I was just unlucky or if all the items are defective. Good luck.
