I've been running a 4x2x2 planted tank without co2 for almost a year just using planted substrate and DIY co2 (yeast) I've decided to branch out into the world of pressurised co2 and have been given a tmc v2 pressure regulator with solinoid and needle valve only problem is the regulator is american cga320 and won't fit my jbl refillable bottle
I have looked into the converters/adapters but I can't seem to find one can anyone help me as I'm stuck and on a budget so can't really afford to buy a new regulator a different co2 cylinder

All American made gas fittings are CGA. Never use teflon tape on a CGA thread connection. What is a jbl refillable bottle? Did you look on eBay?
Forget my last post. I re-read you original post and what I had shown wont work for you because it would be on the high pressure side.

What thread type and size are on your bottle?
