Best Regulator I’ve Used

This regulator is amazing. Sturdy. Made of brass (and not chrome). Dials in super-accurately and stays there. I can’t recommend this enough. Invest in this to start with and avoid the headaches that come with other regulators.

The best of the best in co2 equipment

You likely landed on GLA for your co2 system because you heard they were the best. Thats what brought me to GLA. I purchased this Pro-1 in July of 2019. Its been perfect since day one. I have a few other regulators I can compare it with and GLA is in a class of there own. This Pro-1 is super super heavy duty in all aspects. It weighs about 4x as much as any other regulator I own, its also significantly larger so Im sure that has a lot to do with it. Solenoid and needle valve have been spot on and super smooth. You can totally tell this co2 regulator is 100% built in the USA. Its also UL approved. What is not to love about that?! Good luck trying to find another brand thats UL approved lol. GLA is the best of the best in Co2 equipment.
