Looking for recommendations on how I can repair, or the necessary parts, for my regulator that is leaking. I'm not super familiar with regulator builds or if Co2Art uses proprietary parts for their products.

The plastic tubing connection is leaking, which also contains the needle valve, and are attached to the solenoid. My guess is I need to replace both parts. I've looked at a few pieces on https://www.diyco2regulator.com but not sure of what I would need exactly.

I'd like to build my own regulator at some point similar to the custom made ones in this forum so this would be a great primer for getting started. Let me know if I have left out any necessary info for recommendations or if there is a better source for the parts.

Thanks!

I did contact them recently and they stated that they use standard National pipe threads. So if correct it is very likely that threads on the needle valve are 10-32. Does the needle valve screw right into manifold(Solenoid) or is there a adapter. If a adapter the threads on the manifold are likely 1/8" NPT, and the adapter converts from 1/8" NPT to 10-32. Or they could be 1/4" NPT, you could confirm that if the fitting appears the same size as the main inlet nipple as the industry standard is a 1/4" NPT nipple. But I suspect the needle valve is more likely a 10-32 thread that connects to the manifold directly or if it uses a adapter than it's a 10-32 thread to a 1/8" NPT adapter into the manifold.

How is the o ring?.
10/32 straight threads seal using an o ring between the smc needle valve and solenoid
No sealent (tape or putty) is necessary or effective usually.

It looks like the regulator body is 1/8 npt.
That if correct makes life easier

Full post body kit should be fine if not exactly necessary. A new o ring might be good enough.

This would be just a replacement valve

The leak is coming from the tube connection, not seeing any issues from the o-ring. I think if I just replace the valve along with the tube push connector, that would work, no?
