Pneumatic questions, sorry!

Simple answer. they probably screw together. amount of treads per inch is the same. 14 per inch.

BUT
A CO2 thread has an OD of 21.844 mm. A 1/2 NPT an OD of 21.336mm

Do you want to test the threads with 0.6mm of "diameter missing"?

Can you suggest an altenative way of achieving what I need?

Don know if I'm saying something silly as I'm not sure I fully understand what you're after, but...you could use this to connect to the paintball valve:

and this to connect to the co2 nut:

If I understand right, you need an adaptor to screw on a paintball bottle (female 1/2bsp) to get a 90° elbow to a male CO2 extinguisher thread.
So, yes, I do have an idea. Take an old CO2 extinguisher, drill a 11.5mm hole in the center of the "male thread", tap a 1/2 bsp thread in it, cut it off the old valve , and from there it should be a no-brainer.

[Max]

Don't you mean tap a 1/4" bsp hole?

[maddox10]

Tapping, threading, whatever, cutting a thread in a hole, yes, that is what I mean.

BTW, I do have such bronze "adaptors". I use one of those for pretesting heavy setups with compressed air.

Sorry I wasn't clear- the point I was making wa should said in your post to tap a 1/2"BSP thread which would leave almost no wall thickness, I assumed you actually meant 1/4" BSP- but looking at a valve I have it already has a hole in it larger than 11.5, can't quite remember as not at home right now but it was something like 15mm. But I guess the principle would work with a larger thread.

Hey Max, I think this is what you need:

The male part which mates to your co2 nut is DIN477-6 (0.860")
The female part is CGA320, which is interchangeable to 1/2"Bsp, add a 1/2" angle if you need it that way... hope this helps

Hi guys

I've had a quick flick through some of the pages of this thread I cant seem to find the answer, so I'll just post it here.
Which specific Bürket valve do most of you guys use? I'm thinking its the 5404?

Thanks for responses in advance

[maddox10]

Burkert 5404 1/2 BSP , Normaly closed, 24V solenoid overvolted to 36V.

Main supplier, RS components.
