Quick Union Question

[The Shaman]

When installing a union, which part goes on the flow side the male threaded section or the female ring section? TIA

I honestly don't think it should make any difference. If it did, I would think that there would be an indication on the union like they have on the check valves. Let's see what others have to say.

I agree I do not think it makes a difference.

Damn you guys are fast! :D

Wasn't quite sure, but had to ask. Thanks!

It doesn't matter which direction you mount it. If you are mounting it on a vertical run I would put the female end on top. That way when you take it loose it will stay in place and you won't have to slide it back up to re-connect it.
