Complete Manifold Gauge Set: This complete kit includes a 3-way manifold gauge, 3 color-coded hoses, R134a/R1234yf quick couplers, sealed can taps, adapters, a screwdriver, and a valve core wrench. All packed in a carry case for easy transport and storage

Works with Four Refrigerants: This 3-way AC gauge accurately measures pressure for R134a, R404A, R1234yf, and R22. It is a versatile solution for automotive AC systems, household refrigerators, and small-scale refrigeration equipment

Clear Dual-Scale Gauges: The AC manifold gauge features color-coded high- and low-pressure dials for easy reading. Calibration screws maintain ±1.6% accuracy, while Fahrenheit temperature scales and a sight window help assess charge level during testing

High-Pressure Sealing Hoses: Designed to pair with the AC gauge set, the three 5 ft heavy-duty rubber hoses are rated for 800-4000 PSI working pressure. Gasketed fittings and brass connectors help reduce leakage and avoid loosening during service

Durable Metal Construction: The AC manifold gauge set uses solid brass fittings and an aluminum valve body for strength and reliable sealing. Each component is tested for repeated operation in both workshop and on-site service environments
