Regulator Body Thickness

[Matt F.]

I've noticed something and never really investigated it before!
The body portion of my regulators differ in thickness. I wonder what this means.

SGT500

SGT500

SGT160

Not that this is scientific, but the gauge on the right side of the 500 goes up to 4000 psi, whereas the 160 gauge maxes out at 3000 psi. Perhaps one is simply designed to handle more working pressure than the other?

fjf888,

The 3000 psi high pressure gauges were replaced, according to my source, by the new 4000psi/28000 kPa gauges. You can't get the 3000 psi gauges anymore. Only 4000 psi.

The regulators are all rated to 3000 PSIG.

That said,

it looks like whenever Victor gets a new head engineer, they make changes to the designs and/or ordering system; hence, the difference in body thickness seen in the three SGT models in the pictures above. This, too, was relayed to me by my source.
