  • Re: Pneumatic questions, sorry!

    Ok I see- so I guess I need some hydraulic adapters but first I need to know the threads:
    1) what thread is on the on/off valve? I think it is the same as the one coming out of the valve on a co2 fire extinguisher
    2) what is the thread on the Trevor regulator?
    Thanks

      1. 1/2 or there abouts
      2. the trev reg has a co2 nut. easiest thing to do is to take it off and put on a 1/2 one

        NOT THE SAME!

        on your paintball valve ... a 1/2 BSP nut will screw on but a standard nut is no good for your/our application.

        British BS341 No. 8 ( British Standard 341 Part 1 (.860 in x 14 threads per inch) )
        European DIN 477 No. 6 ( 21.8 mm 14 threads per inch ) for a CO2 cylinder valve /nut.

          Ok- The nut on my (2nd hand) Trevor regulator deffinatly screws onto my Co2 fire extinguisher (quite an old one). The thread on the extinguisher and on off valve look pretty simular but from what woody said there is a subtle difference. I think my on/off valve could screw into my regulator but the thread does start early enough (look at the picture)

          I thought i could file the end of the on/off valve down with a grinder/file so the thread starts instantly- does this sound wise or will it mean i cant use the Valve as it has been modified?

            Do not do that. It will ruin the on/off valve, as the CO2 nut on a Trevor is actualy barely contacting the smaller thread on the valve.

            It's in the same order as trying to put a 1/4 UNC nut on a M6 bolt. hey, it fits, but why does the thread strip?.

            I never treid it, as my gutfeeling tells me it could result in a flying regulator.

              So what do I do to connect them? Where do I get the right nut to replace the co2 nut? And if I change it will the new nut 'come out further' so it will reach the thread on my on/off valve?

                  thats the wrong nut. he needs a 1/2 bsp nut, that one is just another co2 nut.

                  try ebay or rs components for a suitable nut.

                    Jonny is correct the trevor reg has a nut that is the equiv of the daconut I linked to on MY co2 page.

                    The solution isn't that easy with off the shelf parts.

                    I suspect that something could be knocked up with one of these and some thought....

                      Didn't Jonno sell co2 bottles that fit straight into a Trevor regulator?
                      Sorry to keep asking but if I could get an adapter which went straight from the on/ off valve to the regulator would I need a 1000psi pvr?

                          I have a 20oz bottle that the regulator fits directly onto. I don't need it now because I have other tanks for my pneumatic FW so I'm willing to sell if you want it.

                                Would you trade it for a brand new 20oz paintball bottle with pin valve and also my on/off valve?
