The VEVOR 3-Way AC Manifold Gauge Set is a diagnostic kit for testing, charging and servicing automotive and small refrigeration systems. It covers R134a, R404A, R1234yf and R22, and ships as a full kit with three color-coded 5 ft hoses, quick couplers, can taps, adapters, a valve core wrench and a carry case. Dual-scale gauges with Fahrenheit readouts, sight windows and calibration screws target ±1.6% accuracy, and the rubber hoses are rated 800–4000 PSI with brass gasketed fittings. It suits DIYers and mobile techs who want one kit across several refrigerants; pro-grade sets from brands like Yellow Jacket or Robinair typically cost more and are built for heavier daily shop use.

Owners of VEVOR manifold sets generally describe them as solid value for occasional AC work, with the included couplers and case singled out as useful. Complaints tend to focus on fittings and hoses that can leak or loosen over time and on gauges that may need recalibration.
This 3-way manifold gauge set is for pressure testing, charging and servicing automotive and refrigeration air conditioning systems. It works with R134a, R404A, R1234yf and R22 systems, including automotive AC, household refrigerators and small refrigeration equipment.
The high- and low-pressure gauges have dual scales and are color-coded for easy identification. Fahrenheit temperature scales and a built-in sight window help with system monitoring. Calibration screws help maintain ±1.6% accuracy.
The valve body is aluminum, and the fittings are solid brass. The three color-coded rubber hoses have brass connectors with gasketed fittings to help reduce leaks. The kit comes in a carry case for storage and transport.
