Hi, im wondering if someone can help me find the right thread size. I have the gla pro with a single bubble counter but im wanting to split to 2 tanks. Right now i just have the line tee'd and its less than ideal. I domt want to pay an arm and a leg for gla's manifold block ($250)

So the bubble counter on the needle valve is 1/8" and im wondering what most of the generic splitters size is? Im usually good at researching but i cant find much info. My plan was to use some sort of bushing (expander/reducer) from the 1/8 to whatever the generic splitter are. My guess is theyre 1/4 but hard to tell from pictures and the descriptions dont say.

Such as these

Rather than trying to guess the sizing of those splitters, you could probably keep the 1/8" fitting, and get a 1/8" needle valve (Fabco makes one for around 30 bucks (Canadian dollary-doos).

Splitting off one NV will be very frustrating in practice. The feed rate will tend to be very different between the tanks. I just bought an extra manifold block from GLA for 70 dollars and expanded my single NV system. I guess you could also just get a 2 output NV though. Eitherway you can't control two outlets with one control valve and expect good results.

edit: I got this one. You can unscrew the manifold block you have right now and it slides onto the screws on top of the original one. No need to purchase a double block or anything like that,

but it looks like they have been raising prices a lot.

i believe these types screw into your existing needle valve, if your needle valve looks like the ones on milwaukee or azoo regs.

G1/8..is listed for it to mate to.

Thanks for the replies. After lookimg at 1/8 couplings at homedepot i think its even smaller than 1/8 (where the gla bubble counter screws into on the reg)

A double gla manifold on a canadian website is $250!!! Might as well just buy another regulator at that price.

Seems as though im in a pickle

You seem to be missing some pieces in between the bubble counter and the regulator (needle valve, solenoid)

The fitting from the regulator to the solenoid is typically 1/4" or 1/8".

The fitting from the solenoid to the needle valve is whatever GLA uses, though it is commonly 1/8" as well.

From the needle valve to the bubble counter, it is whatever GLA uses. This might be 1/8", but you mentioned that it is smaller.

If this is the case, the easiest solution is to buy two needle valves, just use a Y or T splitter, and get two bubble counters that fit the new needle valves.

Fabco makes reasonably precise NV-55 in 1/8" sizes, so this would be a cheap alternative. Should cost under $80 for the needle valves and all the fittings.

Fabco makes an NV-55 using the same #10/32 ports. You can find adapters for them to standard NPT sizes.

However, the problem with #10/32 was that they were quite fragile; a bump would often shear the connection clean off. This is why most people have shifted to using 1/8" NPT at the smallest now.
