Cam F Will Not Screw Into Ball Valve - Need Help

[Jiffster]

I have a new 3 piece ball valve and cam F fitting. The Cam F will screw in about 1/2 turn and the stops. Threads look fine.

I'm afraid to torque it with a wrench. Don't want to screw it up.

Any advice?

Wrap the threads with Teflon tape first.

^What Bobby said.

Could be a burr on the threads.

Check the pitch:
Try taking the cam F and overlapping the threads (place the threads of each male fitting into the other fittings threads: peak to valley) with another male fitting if you can, this will show if the peak to peak is out of whack.

Also, have you tried another fitting with the female threads on the 3 way valve?

If you crank that on without tape it will leak and you'll never get it off

Ami seeing right that there is no tape on the other side of your valve either? Oh oh

Bobby,
I took the tape off to see if that was causing the problem. Still won't turn.

Should I wrench it to get past the trouble spot?
