Hi,

I have a brass utility tub faucet that has 1/2" female IPS Unions. I am using Sharkbite fittings and the closest I can find is a mnpt sharkbite.

Can I join the male mnpt to the female IPS? If not, what other solutions ae available?

Thanks

Rich

Ayuh,..... They're both the same threads, so they should just screw together with pipe dope,.....

That's what I thought at first, but found that most sources advise of not joining the two types.

The IPS, also called NPS, is a straight thread, while the NPT is a tapered thread.

Research shows with NPS a gasket or O ring is suggested.

Rght, but the male npt will not screw down low enough to engage the ring.

So what I was looking for, is what they showed in the product picture. A fitting that joins standard 1/2" copper pipe to a IPS (NPS) thread. That picture is exactly what I had in mind.
