Co2 Gauge Replacement

[darren996]

Hi all
I am getting bits and pieces together for kegging and I have two co2 regs. The gauges on these read 0 to 315 bar. Are these regs usable ? Can I replace the gauges with lower rated gauges 0 to 6 bar?

Total noob to kegging so any help would be great thanks

One will be for pressure in the tank and the other indicate the outlet side pressure which you set accordingly.
They can be replaced but only the adjustable one will be of any advantage to you.
I think I have  one spare gauge in shed you can have it. I have tubing also if required.

Also have spare nitro regulator used once if you have any use for it.

Thanks BB. One has bar and psi and the other has litre per hour.  i will hook it up to co2 tonight and see which one is adjustable.

This is the one I have but it's in bar not psi so hard to get exact amount psi ur carbing or serving pressure and smaller ones are designed for front of Guinness taps..... so sorry brother.

You need the larger one in psi. Cheap enough to buy think

Cheers Bb, I just got one there on eBay.  just wanted to know if I could swap them out. Is 6 bar the standard max beer reg pressure? Would you ever use 6 bar ?

[Beerbuddha]

2 bar would be Max I have used. 28psi. It's on my to-do list to replace serving gauge with digital because I'm mad like that.

[darren996]

Yeah I saw a few of those digital gauges on eBay, your gonna need a bigger shed soon enough

I ordered a 4 bar one from the uk so I should have one next week. Thanks for the help.

And your gonna need divorce lawyer if you don't hide all the brewing receipts

Ha, can you recommend one.  It's bad when you are on first name basis with most of the couriers in the country

Hold on there!

If there's only one gauge (reading up to 315 bar) its highly likely its a mixed gas reg (as the commercial ones don't have a Low Pressure gauge - that is set by the installer)

If you have two gauges and one is calibrated in liters per minute then its a welding gas reg.

If it has a male nut then its mixed gas/argon/oxygen

if it has a big female nut then its CO2

Cheers will

Here's a pic, what is it and can I use it? Thanks

[Will_D]

Its a welding reg (hence the useless calibration on the right hand gauge). Left hand is the high pressure gauge and will show a steady 60 bar or so on CO2.

Why do I say the RH gauge is useless? Because its a pressure gauge and for welding it cannot indicate flow. You use a flow-meter for that (ball in tube yoke).

However the good news for brewers is that it is a pressure gauge and will show the pressure that the reg is set to. This is adjusted by turning the black knob on the reg. Clockwise increases, anti-clock decreases the pressure.

You can assume it reads from about 0 to 100 psi. So just multiply the black numbers by 3 and it should give you approximate psi.

thanks for the info Will
