Engineered for HVAC technicians, refrigeration service crews, and automotive AC repair shops, this 4-way manifold gauge set tests R22, R404A, R410A, and R12 systems with independent vacuum and refrigerant valves for evacuation, vacuuming, charging, and recovery. Color-coded high- and low-pressure dials with calibration screws hold ±1% accuracy across daily service, and Fahrenheit scales plus a sight window assess refrigerant charge during testing. Four 5-ft rubber hoses rated 800 to 4000 PSI seal under gasketed brass connectors that resist loosening on the road.
R22 R404A R410A R12 Support: Pressure testing for R22, R404A, R410A, and R12 covers home central AC, commercial refrigeration, and legacy fleet AC systems.
1% Calibration Accuracy: Color-coded high- and low-pressure dials with calibration screws hold 1% accuracy on Fahrenheit and pressure scales for clean charge readings.
5-ft 800-4000-PSI Hoses: Four 5-ft heavy-duty rubber hoses rated 800 to 4000 PSI seal under gasketed brass connectors that resist loosening during road service calls.
HVAC, Auto, and Fleet Use: Test home central-AC charge on a service route, evacuate a parts-store walk-in cooler, or recover refrigerant on a fleet truck AC repair call.
Aluminum Body, Brass Fittings: An aluminum valve body and solid brass fittings handle workshop and on-site environments without warping, with rubber covers on the gauges.
