49974 A2L 4-Valve Test and Charging Manifold, 3-1/8" (80mm) Gauges, Compatible with R-32 R-410A R-454B, HVAC AC Manifold Gauge Set (Hoses Not Included)

49974 A2L 4-Valve Test and Charging Manifold, 3-1/8" (80mm) Gauges, Compatible with R-32 R-410A R-454B, HVAC AC Manifold Gauge Set (Hoses Not Included)

• Accurately Adapted: 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. For maintenance, charging and recovery of HVAC/R systems.
• Clear readings： 49974 Test Charge with easy-to-read 3-1/8″ (80 mm) steel case red and blue. The large 80mm dials are vibration-resistant and accurately display high and low side pressures ,1% accuracy (Class 1). Allowing HVAC technicians to provide quality and efficient services.
• Durable and Robust: Featuring a lightweight aluminum alloy frame for easy handling, this design delivers enhanced strength and reliability. The overall structure resists impacts and aging, making it ideal for high-frequency use in construction sites, repair shops, and similar demanding environments.
• Built-in sight glass for stable reliability: Streamlined non-slip handles ensure precise control, while the sight glass provides clear visibility of refrigerant flow during charging and recovery. High-precision mechanism and sealed construction deliver sensitive pressure response with minimal error, guaranteeing accurate refrigeration system charging and maintenance data for safe equipment operation.
• Four-valve design ensures system purity: The fourth hose can simultaneously connect to high-pressure and low-pressure sides, storage tanks, recovery units, or vacuum pumps, enabling diagnostics, vacuuming and charging operations without hose replacement. Facilitates replacement of old gauges and tool upgrades, offering high cost-effectiveness.
