Help differentiate two Regulator Setups

[awoitte]

Can someone help me identify (if any) the difference in quality between these two regulators?

Obviously, the barb on the outlet on one is larger than the other, which I'm not sure if that makes any difference for gas purposes. Other than that, the larger barb outlet seems to have a smaller regulator face.

I just don't know by looking at these, or by the brand listed on them if there is any difference in quality, performance, etc.

Thanks,

They are both the same Taprite regs but one has a replacement gauge.

Would you expect one to function better than the other? The replacement ones have larger numbers to read, but curious if one would be expected to work/last better or longer than the other

I wouldn't expect any difference at all.
Gauges fail. I've lost a couple over the years. NBD, replace with a similar scaled version and good to go for ~ $8.

Gas side barb size only matters for the tubing used. 3/16" ID tubing works just fine, as does 1/4" or 5/16". fwiw I run 3/16" ID braided Tygon for gas...

Cheers!

One other difference is the one with the replacement gauge has 1/4" MFL valves, while the other only has the barb. If you are using 1/4" FFL fittings with your tubing, those will be more convenient.

I've personally changed out all my gauges for Winters P9S gauges which have higher accuracy and can be re-zeroed, which I really like. I also have a 4" test gauge that is accurate to .25% of span that I use to calibrate the gauges about once to twice a year to check for drift.
