    that's where i'm stuck.
    I bough this Gas pressure contoroller to go away from regular U gauge. It come without adaptors.
    So, because I have one (left) from Pressure hose connection set, which comes with 320b and second (right) from B3 probe set (B2 angled probe, B1 gas cooker probe) I decided to use Left one.

    But after zeroing, I tried to raise pressure. But it makes just psss and that's it. So the leak is actually here (shown on picture). When I swapped them - no problem. Works fine.

    So I see you are useng the same adaptor, but not getting same problems as I. So I will ring Testo on monday and try to get answer from them.

    Got an answer from TESTO
    The ribbed adaptor is for gas analysis B3 probes, the smooth is for pressure.
    Can't see why they done it, but this is the way how it is.
    Hope this helps.

    What’s the difference between using the nipple and the probe connection?
