had the same thing happen to me...
I don't believe I said it was glass, I said it was junk.Pretty sure the JBJ bubble counter is not glass
What?I don't believe I said it was glass
IMO glass would fall apart if cracked multiple places, plastic like my JBJ bubble counter would still hold together when cracked although it would leak.I'm talking about multiple cracks in the glass cylinder just tighting by hand.
You might have that problem with any check valve initially. I have found you need more pressure the first time you use the check valve to open it up. The JBJ bubblecounter screws onto the needle valve assembly, and it has a rubber gasket to prevent leakage. You do not have to tighten it very hard to get a good seal, over tighten it and you can break it rather easily, but there can be manufacturer defects which can cause leakage around the fitting or cracks in the plastic. Thats why I find it easier to use a cheap inline bubblecounter. Any plastic bubble counter will have its stress point. Glass is even worse. These ADA and ADA rip off solid glass bubble counters... you have to be real carefull how much force you use when putting on the tubing. It can be an expensive mistake if you exert too much pressure.I've got a JBJ, my favorite thing about it was that the 10 psi I run my system at wasn't enough to get CO2 past the flapper check valve. Had to drill it out. Quality stuff.
