Our take on the Bolton Tools 3 Way R134A AC Manifold Gauge Set

The Bolton Tools 3 Way R134A Manifold Gauge Set is a diagnostic tool for automotive air conditioning systems that run on R134a. It handles testing, evacuation and charging, with brass connections, field-recalibratable gauges, an extra-large sight glass and a heavy-duty hanging hook. It comes as a kit with a pair of quick couplers, a 60-inch charging hose set, a valve core wrench, repair kits and an adaptor. It suits DIYers and working techs servicing R134a cars; against basic two-way sets it adds a third service port and field calibration, though it is limited to R134a and not newer R1234yf systems.

Questions and answers

What is a 3-way manifold gauge set used for?
It tests, evacuates and charges automotive AC systems. The third port lets you connect a vacuum pump and refrigerant source without swapping hoses.
Does it work on R1234yf systems?
No. It is built for R134a refrigerant only. Newer cars using R1234yf need a different manifold and couplers.
Can the gauges be adjusted if they drift?
Yes. The gauges can be recalibrated in the field, so you can bring the needles back to zero without sending the set out.
What comes in the box?
The manifold gauge, a pair of R134a quick couplers, a 60-inch charging hose set, a valve core wrench, a pack of repair kits and an adaptor.
Can I use it to recover refrigerant?
It can be part of recovery work, but it does not recover refrigerant by itself. You still need a recovery machine and tank.
Is it good enough for professional use?
It covers the basics for R134a service with brass connections and field calibration. Techs who work on many refrigerants will want a set that covers R1234yf too.
