Question how to connect manifold to regulator (diyco2regulator)

I bought an upgrade (diy kit with solenoid and needle valve from diyco2regulator.com) for my Oxyturbo (single stage) regulator.
The co2 manifold needs a 1/8"MPT nipple in order to connect to my regulator.
I can't figure out what thread size I need on the side of my regulator. It's smaller than the 1/8"MPT nipple and not 'cone shaped'... Hope someone can help me out!

One the old fitting (valve) is there an o ring at ????

Looks to be straight threads w/ flare fit..
That's going to be an id problem..

Your NPT stuff isn't going to fit..

Your straight could be any number of standards British, American, Metric ect..

Lifes a gamble..
Can't ever eliminate most risks unless you let others do it for you..
you "probably" won't have the o/p's issue.. That reg looks british/Australia based..

Really!!! picked the Fabco over the swagloc?????
Yea, after getting all the parts probably 2x as expensive. but it's shiny white..

Thanks a lot for your answer. I'll try to get in touch with oxyturbo, maybe they have a solution. This is indeed a european regulator but I didn't expect that the connection from the regulator to the manifold would cause a problem..

This post body kit came with the Fabco, I don't know anything about swagloc. Suppose I like shiny white..

Yours is 1/4 npt coming out of the regulator.

Just a noob

What is a bit troubling is that it looks to be designed like this:

I bought a 2 stage that needed that specific CGA "type"
The left smooth tapered end is the "seal"..on the straight threaded part..
Straight threads don't seal on their own..

you look to have the same concept on the outlet threaded part..
Can't really tell though.
Finding the thread type won't be near as hard as finding one that seals.
sorry to say you may nedd something from the manuf.

Hey they have some.. not sure if this is correct (and need "handed-ness" type) but looks like you can go to 1/4NPT male..

SHOULD be the body thread type..

Thanks a lot! Looks like the right thread type for the regulator. I sended an email to Tesuco to see if this will work. Thanks

(maybe this could work?

Thanks for your help. Had contact with Tesuco. They said Oxy Turbo generally uses 1/4 or 1/8 BSP for all ports.

I found out that 1/8NPT to 1/8BSPP (parallel) should do the trick for me.

I'll let you know if it worked out.

Take into consideration BSP and NPT are vary similar..
Each will "fit" only one will seal..at least w/ bsp taper and npt taper..

Like I mentioned straight threads do not seal..so it either 1)uses o rings 2) uses other mating surfaces (like I showed w/ the cga ones or 3)will need sealing i.e pipe seal

That's very useful information. The regulator has an (plastic) o ring inside the fitting. If my BSPP fitting is long enough it should seal properly. According to your link the best option is to (extra) seal it with pipe dope because of plastics involved. After reading this I think I will seal the other parts with pipe dope too instead of teflon Thanks again. I'll keep you posted.

Anaerobic resin compounds

Anaerobic resin compounds use a different cure chemistry than solvent-based pipe dopes and do not contain solvents. The cure begins when the sealant is confined within the threads of the metal pipe connection and air is excluded.
suggest you try to find something like this first...
It's expensive esp in larger quantities but can be found for a reasonable price w/ some digging.
https://www.amazon.com/Anaerobic-Thr.../dp/B0089804A6

If not.. normal stuff like Rector-seal should do..

Yea your removed needle valve looked "special"....

Update:
I used the 1/8NPT to 1/8BSPP (parallel) nipple in combination with Loxeal 58-11 and it works great. No leaks and steady pressure. Thanks a lot for your input!
