From post #23:
If you don't want a bubble counter, you can install a hose barb. This is what I recommend b/c they lock the hose on the barb:
Brass Hose barb adapter with locking nut mechanism(these two parts work together)
I need some advice for selecting the appropriate tube fitting. I would like to use an in-line glass bubble counter with at least 2 in-line check valves for redundancy (before & after bubble counter), so I assume I need a tube fitting attached directly to the Ideal needle valve (V52-1-12)? (Please let me know if this will work or not.) Will the B-6MO-1-2 tube fitting attach directly to the V52-1-12 & standard 4/6mm tubing? I just saw from the thread posted below that I would also need B-6M5-4M, right?
Many thanks to Matt for posting this guideline! I will be following the directions closely as I set up my first regulator.
EDIT: I see in the thread link below that I will need B-6M5-4M to use with the B-6MO-1-2 fitting. I guess the directions for the SS-6MO-1-2 are the same for the brass version?
