    Any ideas on what I can do about this? Is ther an adaptor or something i can do?

    The screw on sleve fits fine but the bit that actually inserts into the bottle is very slightly too large. Any ideas?

    I didnt realise the JBL regulator would be any different to a standard regulator.

    Apparently you can get it to fit by reducing the diameter of the male part of the reg with emery cloth.

    I'm sure JamesC explained how somwhere... Hopefully he'll chime in here.

    Really?! Excellent! It is literally a 10th of a ml out but didnt want to go modding it if it was unsafe.

    Yep, just file it down a bit. I've pasted in the following from another post:


    The JBL regulator is slightly oversize for a fire extinguisher (which has an
    international std neck on it). All you need to do is take the O-ring off the
    regulator (carefully!) & have at it with some 120 Grit Wet & dry sandpaper -
    takes about 10-15 minutes just to take enough off for it to fit. Get a fire
    extinguisher, try & fit the regulator & you'll see what I mean & which bit you
    need to "adjust". The threaded collar that you tighten up onto the bottle
    fits fine - its the bit inside this that doesn't go inside the extinguisher neck
    properly. My tip for the day is to buy yourself some spare O-rings if you
    don't have any!

    Its the O-ring that makes the seal anyway ( a tiny smear of vaseline is a
    good idea on the rubber) so don't worry about doing it & the thing still
    works fine on the std JBL bottle - I still use mine for a couple of days
    here & there everytime I run out of the main bottle. You'll take the chrome
    off the nose of the regulator obviously but that is no matter - underneath
    its brass as would be expected & you don't see the bit you need to adjust.
    Lord alone knows why JBL made the thing slightly oversize - probably to make
    sure we had to use their hideously overpriced CO2 I expect!

    THanks for that James,

    Any idea where to get spare 'O' Rings?

    A JBL stockist can probably get them for you or you could do want I did and email JBL in Germany and ask them very nicely where you are able to purchase them as you've broken the one you have. They offered to send me some FOC which I gladly accepted. Fantastic customer service.

    I know some people moan about JBL but I think they are great. Had my regulator coming on four years now and it has performed faultlessly. One thing I love about it is these O rings. Great idea as it means you only have to tighten up the regulator to the CO2 bottle with your fingers with no worry of any leaks.

    James

    I know george uses the JBL reg etc along with loads of other JBL stuff, what i've seen and used of it it all seems real good quality.

    Yeah, can't fault the build quality. I emailed them when my PH probe went belly up 2 months after buying it and they sent me a replacement along with a kilo of different fish foods for my troubles! Quality.

    They just need to sort out their liquid fert range now...

    I've got a JBL Easy 2 CO2 kit with the disposable bottles and solenoid and it's been great for me. Got it set up with a beetle counter now on the side so the bubble rate can be counted dead easily. Certainly been impressed with JBL, except the diffuser tower thing they include with the kit...

    just for the record, my aquamedic regulator also was slightly too big, removed the rubber o-ring, sanded it down, replaced the o-ring and it works like a treat.
