    Bellman CX25P pressure query..

    i bought a bellman cx25p and package doesnt include any pressure gauge with it. im so pissed and im still waiting for the sellers reply.

    i have a question regarding PSI. if i want to replace it with a 3rd party gauge. what would be required PSI? all i know is that it indicates 5bars on the original bellman pressure which i dont have..

    Yes, hi, how are you? Welcome to the site.

    Not 100% I'm sure what 'required PSI' is, but 1 bar = approx 14.5 PSI.

    thanks. ive been reading here for a while now.

    i used a converter too. so if im going to get a 3rd party gauge. it should be around 60-70psi.

    my seller will send a gauge.

    i have another question. what is the size of brass button connection of bellman's gauge? is it 1/4 or 1/2 npt? i will still get a 3rd party gauge and will make the original gauge as a back up..

    I’m not 100% sure, but I would imagine the gauge fittings on the Bellman would be BSP. Have you been told they’re NPT or are you assuming? Most likely size is 3/8BSPP, but as I said I’m not 100% sure.
    I wouldn’t recommend getting a 3rd party gauge. I looked into this in the past and to get a gauge that can tolerate the temps generated by something like a Bellman is really expensive. You can buy genuine Bellman gauges as a spare part from suppliers so if you want a spare this is what I suggest you do.

    so i really need to wait for the original bellman gauge. NPT is what is written on the gauges specs but i'll go with your advise. i shove a stainless bolt on the pressure gauge port for me to use it. its working fine now without the gauge. more like guessing the pressure..

    Ok, maybe it is NPT. I suppose its just as likely as BSP. Di Bartoli have genuine Bellman gauges as a spare part for $40.

    im not sure if the bellman's gauge is NPT or BSP. it's the 3rd party gauge that says NPT.

    Ah right. In that case you’d better check before you buy something as I still think BSP is the most likely thread type. I don’t think $40 is pricey at all for a gauge that you know will work, and as they are readily available I don’t think there’s much point buying a spare for it to sit around and never get used. I know you can pick up gauges from as little as about $10, but as I said above you need to check the operating temperature range. When I looked into this a few years ago it was very difficult to find a gauge with a high enough temp rating and when I did it was well over $100. So while you’d be able to get something cheaper than the genuine one it’ll be wasted money if it doesn’t work properly or dies quickly. It’s a bit weird that your machine arrived without the gauge in the first place, I hope the seller has sent you one by now.
