Miller Electric Regulator, Cylinder, Nitrogen, CGA-580 (30-450-580)

Great product at a reasonable price, I looked locally, way more $

This regulator works great. I use it every day doing ac

High quality product, connector do not work with European bottle standard. I had to adapt connection by replacing the connector to EU standard. Nevertheless the regulator is well finished and valves operating with great accuracy.

The quality is nice but not that of a $1,000 model. Easily suitable for uses Miller lists as uses. The lowest psi range may be "touchy" if you are thinking about un-ilsted uses. It came NIB with instructions. The quality of the mating surfaces (no leaks) is obvious. A great buy for it's listed uses.

I can only get 400 psi out of it on a brand new tank. I need the full 600 from it for my shocks. And too late to return. Not happy!

I looked at many nitrogen regulators and this one had the best feaures. For purging an AC system you can throttle it down to a 1-2 pisg setting and will hold that value. For high pressure testing it works great also. The regulated gauge reading is not exact but close enough for most testing. Would suggest using another guage for comparison if necessary. A very rugged regulator made in the USA.

The regulator only went up to 390 psi, but I inserted a spacer and it now performs well. Otherwise a good quality product for a good price.

Works great, but I was mistaken as I thought the second gauge was a flow-rate and not a pressure. Does not really matter, just have to guess some on your flow rate so you don't run your tank out too fast. Smith makes awesome stuff and this is the best price I've found anywhere.
