How to build a Victor VTS253b-320

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)
B-400-1-2
B-405-2
------------------------

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?

I think you are smart to opt out on the JBJ-style bubble counter. The check valve will fail at some point...it's just a matter of when.
I use ADA in-line glass bubble counters (not the beetle counter, but the simple ADA glass bubble counter). I also use the ADA gray Parts kit per ADA's instructions. This comes with a high quality plastic check valve which is to be placed underneath the bubble counter.

These part numbers DO NOT work with 4mm/6mm tubing:
B-400-1-2
B-405-2

I have removed these from post # 23. I don't want anyone to be confused.

ALso I have removed the Bigway NPT part numbers. Bigway charges way too much for shipping and the parts are of a lesser quality. I recommend and use Swagelok brass and stainless parts.

If you want to save money, take a trip to your local ace hardware. they usually have a pipe fitting section.

This is the correct part number for 4mm/6mm tube adapters with a male 1/8" npt thread (which screws into the ideal needle valve or a check valve).

You can use a B-2c2-1/3 or SS-2c2-1/3 Swagelok check valve which will sit between the ideal valve and your tube adapter.

Hope this helps.

I just converted both my regs to the SS-6M0-7-2 tubing adapters. This deletes some unecessary parts and shortens the whole post body.
