  I have and only use GL Aco2 cylinders. Always nice and shiny.

  I think we have a total of 8 cylinders for our fish farm and all of them from GLA except one steel one we use. GLA is always nice and shiny new with USA made valve.

  The best co2 cylinders

  Posted by Nathan Caldwell on 24th Jan 2024

  My 3rd GLA cylinder. I only buy HLAcylineers because they are fully 100% American made. It’s also not painted. When the cylinder is painted your not likely able to get it filled due to the paint voiding ability to be filled.

  GLA Co2 Cylinders are the very best. 100% made in the USA.

  Ive always bought GLA cylinders for two decades now. I have quite a number inside my house and outside my house for my pool system. I found GLA cylinders to be the best because they sell so many the hydrotest dates are very fresh so you get many years of use. Not only that GLA also has the little seals I like to use. I just wish they stocked the larger sizes. I realize beyond this size they get cumbersome and extremely heavy.

  These are the absolute best of the best in cylinders.

  Made an ass of myself buying a used cylinder somebody refurbished and painted. Well guess what? Nobody will fill a painted co2 cylinder. Lesson learned. GLA has a good price, it was made in the USA and has fresh hydrotest dates. You cant possibly want more. Word of caution, dont buy a painted cylinder. Nobody is going to fill it.

  First class co2 cylinder.

  I own 4 co2 cylinders from GLA and they are always the best. Im comfortable saying that because they are as well made as they possibly get. Fully American made with American made valves. Its everything you need from a cylinder.

  I own 3 GLA co2 cylinders and all are exactly what you see. They have a great price and the hydrotest dates are always so fresh so you get a solid 5 years. Packaging and shipping was swift.
