Tank Valve Thread Question

[RandomGuy1]

I have a set of luxifer 80's that are doubled up. I also have a set of faber hp120s that are singles. I am thinking that I should be able to use the manifold and valves off of the 80's and double up the 120's, but I am unsure of the threads. Will this work? I can't seem to find any information on the threads.

if they are fabers, the valves should swap over with no issue

Maybe and maybe not. Faber has used some odd threads in the past including British Pipe thread which are really odd ball.....took me weeks to figure out what they were. A SAE 7/8 valve will almost fit but not quite. Odds are they are standard SAE 7/8-14 but they also could be metric M25x2 which is real close to a 7/8s thread and can be very dangerous to mix the 2.

the fabers are only about 2 years old, so I suspect that tbone is correct. Thanks for the info!

2yrs old are definitely ye old standard 3/4" valves, available from anyone. Swap em on over. I would recommend breathing the tanks down as low as possible and bleeding them very slowly preferably near a compressor though so you can fill them back up quickly. We are at the point in the lovely Carolinas where it is hot and humid and you can have condensation inside of the tank if you drain them too fast.
