49974 A2L 4-Valve Test and Charging Manifold Only, 3-1/8" (80mm) Gauges, for R-32/454B/410A, HVAC Manifold Gauge, A/C Manifold Gauge (No Hoses)

49974 4-Valve Test and Charging Manifold designed specifically for high-pressure, new environmentally friendly refrigerant systems R-32, R-454B, and R-410A, ensuring accurate and reliable readings.The four-valve design allows simultaneous connection to the high and low pressure sides, refrigerant tank, recovery unit, or vacuum pump. Throughout the entire diagnostic, recovery, vacuuming, and charging process, there is absolutely no need to disassemble or switch any hoses, greatly improving work efficiency and eliminating the risk of refrigerant leaks caused by frequent switching.By flexibly controlling the four valves, you can easily isolate the instrumentation section from the system, or isolate the high-pressure side and low-pressure side separately. This makes accurately locating system leaks and testing individual compressor functions simpler and more accurate than ever before, making it an invaluable tool for troubleshooting complex commercial systems.Reduced downtime, labor cost savings, and eliminated refrigerant waste will quickly make this meter set one of the most cost-effective pieces of equipment in your toolbox.

• Accurately Adapted to New Environmentally Friendly Refrigerant: The 49974 4-Valve Test and Charging Manifold is equipped with a 3-1/8" (80mm) color-coded pressure gauge, specifically designed for measuring R-32/454B/410A refrigerants. For maintenance, charging, and recovery of HVAC/R systems.
