    Does anyone have the link to the part that can convert the long heavy regulator from the truck supplier to the shorter style.

    apologies, I can’t think of the name of the company that makes the truck regulators that are available to us.

    I thought @Kotori87 had it at one point. Not sure though.

    The regulators are from Poly Perfomance I wonder if @bsgkid117 would have the info for the conversion or know where to find it.

    It cuts the length down by about half.

    love it. hey so how'd you get it on? does it need that nylon spacer to work like the pre-conversion?

    I just put a liberal amount thread tape on and tightened as much as I could.

    no. It does not need the nylon spacer anymore. It uses the O-ring on the bottle valve for a seal. I can’t remember the specific name of that connection type.

    So technically according to the IRC rules, you have messed with the high side of the regulator which is a big no no. I haven't looked in the rules recently but I know it used to be in there. Ya might wanna take a look.

    What was replaced/modified here is a standard CGA gas bottle adapter, I would make the argument that it's not actually part of the regulator at all.

    I interpret 'high side' as not messing with the internal components in order to get more/less than 150 psi out of a stock regulator.

    I would disagree. They removed a component of the regulator that was installed by the manufacturer. Therefore they messed with the high side of the reg.

    in your view, if a regulator breaks and we can replace the part, that’s illegal because it wasn’t repaired by the manufacturer?

    I’ll make a note to bring an extra regulator to NATS. Just in case the CD tells me to change it.

    "The regulator serves to divide the system into a high-pressure side, consisting of the CO2 tank and pressure relief valve."

    As the "high side" is defined, consisting of the CO2 tank and pressure relief valve (burst disk), no high side components were modified here.

    The historical interpretation (your interpretation) of "high side" has been incorrect. If we ran with your interpretation, shimming regulators and such at NATS to pass check in would be illegal.

    GOOD. DAY. SIR. :laugh:

    This is always good practice. Two is one, one is none, ideally bring 13 of everything and you should survive the entire week.

    Here is the rule: as long as everything on the high pressure side is rated for that pressure then it is not a violation of the rule set below.

    The reason it becomes an absurd interpretation in this case is because we can just go back to that manufacturer and ask them to sell us. Just the regulator portion of that initial assembly do exactly the same thing and then comply with what you're asking. That is why your interpretation makes no sense.



    2. All CO2 systems must have a commercially manufactured pressure regulator set to no more than 150 PSI. The pressure regulator must be connected to the tank using only manufactured hoses or unions rated for CO2. The regulator serves to divide the system into a high-pressure side, consisting of the CO2 tank and pressure relief valve, and a low-pressure side, consisting of a distribution manifold, poppet valves or solenoids, and conventional R/C BB cannons. Items on the low-pressure side of the regulator do not need to be commercially manufactured or certified.
