Replaced the old union to be sure of the water heater connection.

Threads were clean, well machined, and the mating surface didn't leak any natural gas after being hooked up to my gas water heater.

I used this fitting as part of connecting propane to a wall heater at my cabin. A little pipe tape and no leaks on the first try.

It's a pipe union. It worked and doesn't leak.

These things are life savers. For $15, I’ll buy a mega press coupling.
