I've read conflicting information about how tight the Co2 regulator should be, hand tight or as tight as possible with a spanner?

It's 800psi I guess so needs to be tight but then again the sealing ring could be damaged if too tight.
 
Hi madlan

It depends which type you have.
Some have an 'O' ring and some have a flat washer to make the seal.
The 'O' ring type only have to be 'nipped up' because the 'O' ring makes the seal, and regardless of how tight you do it up, you are not tightening up onto the 'O' ring.
The flat washer type need a spanner as it's the flat washer that makes the seal.
I have the JBL 'O' ring type and the 'nut' that holds the reg onto the bottle is not even hexagon (for a spanner to fit), it is round :wideyed:
 
Mine's tightened by hand and now I couldn't remove it without a spanner. I must be like super strong to get it on so tight.....yeah, that must be it.
 
My tank pressure is 800 psi as expected but the working pressure reads 70 psi, is this too high?
I don't think this UP regulator can be adjusted?
 
Hi madlan

This sounds a bit on the high side to me.
70psi = 4.8 Bar. Most are set to run between 1.5 and 2 Bar (22-29psi).

I can't help with the adjustment as I haven't used the UP regulator, but there are plenty on here who have. Maybe they can chip in to advise if it's adjustable.
 
Hi all

Oh dear, is 70psi going to be too much? Broken regulator?

It may be set that high by the manufacturer.
I would try it and restrict the flow with the needle valve and see how it goes.
I believe the UP atomiser needs a decent bit of pressure to work correctly, maybe they've taken that into consideration.
Just a thought.
