Is the full scale 500 psi (as pictured) or 350 psi (as in description)?

*30", 0-350 psi - retard protection to 500 psi

Will this gauge fit on my 42006 series 41 manifold? I got the wrong gauges (r22, 134a, and 404a) and I need the 410a.

I see no reason why it shouldn't fit...threads should be the same...but you will need to be able to hook it up to your AC system and those end connectors may be your problem...make sure you have the proper end fittings that you need for your system. I have multiple gauges for mine that I can interchange.

Hi i need a low side and high side for: R134A,507 and 404?

You need a gauge, gauge and hoses?

Will this work for R134?

I'm a 20yr tech. It will work for any refrigerant really... it just doesn't give the saturation temp of R134a. But it will give pressures which is the main purpose of gauges.
