Review on AURELIO TECH Manifold Refrigerants Adjustable by Steven Guevara

I have an old 1992 truck that had the AC pump burned out after 29 years of faithful service. I decided to upgrade to R134a as R12 is obsolete. One thing I read in other reviews is that banks with R134a cannot be connected. I had trouble understanding how it works, but the fitting is included and works great when you attach it correctly. A very nice feature is the separate hose (black), valve and connection for the vacuum pump. Many sensors don't have this and it's a nice feature in this set. You can connect everything right from the start and don't have to deal with switching off the vacuum pump to fill. Good quality valves and gauges. The anodized aluminum valves are much nicer than the junk plastic on my old kit. Here you will find everything you need to convert from R12 to R134, except R134a nipple fittings for retrofitting. You can find them pretty cheap here at Revain if you need them.
