Review on 🌡️ Yellow Jacket 42006 Series 41 Manifold with 3-1/8" Gauge, PSI, R-22/R-134a/R-404A by James Turpin

These gauges are of the high quality you would expect from a yellow jacket. There is nothing more to say here. If you use them in R134A vehicle air conditioning systems, you will need couplers, a canister tap and a vacuum pump. I would like to recommend the kit I bought for myself: 1. Mastercool 85510 r134A can embed valve screw model 2. Mountain 8201 R-12 to R134A3 conversion kit. Robinair 15510 Vacumaster Single Stage Vacuum Pump, 5 CFM You should be more than happy with this setup.
