VEVOR AC Manifold Gauge Set for R134a R404A R1234yf R22 — 3-Way Kit with 5 ft Hoses, Aluminum Body & Quick Couplers

VEVOR's AC Manifold Gauge Set is a complete three-way HVAC charging and diagnostic kit compatible with R134a, R404A, R1234yf and R22, supplied with 5 ft color-coded hoses, quick couplers, adapters and a hard carry case.

This professional-grade manifold set brings workshop durability and field portability together so technicians and DIYers can test, evacuate and charge automotive and small refrigeration systems. The kit centers on dual-scale, color-coded gauges and a solid aluminum manifold body with brass fittings, plus sealed can taps and multiple adapters for common service situations. Everything is organized in a molded case for easy transport and secure storage.

How accurate and readable are the gauges for diagnosing AC systems?

The set uses clear dual-scale dials with separate high- and low-pressure readings, Fahrenheit temperature conversions and a sight window to help evaluate charge levels. Calibration screws allow precision tuning to maintain the stated accuracy so you can trust readings across repeated service tasks.

• Dual-scale, color-coded high/low pressure dials for fast interpretation
• Calibration screws for maintaining ±1.6% accuracy
• Fahrenheit temperature scales and a sight window for charge assessment

Which refrigerants and systems can I use this manifold set on?

This VEVOR kit is built to work with four widely used refrigerants—R134a, R404A, R1234yf and R22—making it suitable for many automotive AC systems, domestic refrigerators and small commercial refrigeration tasks. Included quick couplers and adapters let you connect to common service ports without improvising fittings.

• Compatible with R134a, R404A, R1234yf and R22 refrigerants
• Includes R134a/R1234yf quick couplers and multiple adapters for ports
• Sealed can taps for safe access to refrigerant cylinders

Are the hoses and fittings durable enough for workshop and field use?

The kit’s three 5 ft heavy-duty rubber hoses are rated for high working pressures and use gasketed fittings to minimize leaks. Solid brass connectors and an aluminum valve body deliver mechanical strength and reliable sealing during frequent connection and disconnection cycles.
