Where to find the right sized compression nuts for CO2 equipment?

    The plastic compression nuts that come with the UpAqua atomizers/bubble counters or the GLA atomizers/bubble counters have been breaking on me. They crack and then split in half. I had one stainless steel nut that came with the fluval CO2 system I tried and a brass one that is on the JBL bubble counters. I've looked at a few hardware stores, my local welding supply store where I get my CO2 refilled, and an auto parts store for the correct size...however none have it.

    Where can I find these things? I'm out of replacements and now have a leak in one connection at the bubble counter because there is no compression nut.


    Thanks for the help!

    None of my business, but you may be tightening them too tight-I don't think they prevent leaks as much as they keep the hose from falling off the tiny barb. Put it on finger tight and do leak check-if no leaks don't tighten any more.

    Maybe these will fit--cheaper than buying new atomizer:

    Up Aqua-should fit:

    Brass-there are two compression nuts but may not fit:

    thanks, i probably did tighten it too tight, but they break so easy it is tough to get it snug without too tight. They haven't broken on the atomizer, just the bubble counter.

    It would work, but probably wouldn't look as sharp. A plastic tie would probably work as well, but we all know a stainless steel nut would look better:)
