R410 22 134A Air Conditioning Pressure Gauge, 3 Way, Air Conditioning Diagnostic Pressure Gauge Hose Assembly for Refrigerant Filling

1. Connection: Each end features a 1/4" female brass thread for easy connection. The red hose connects to the 1/4" male thread on the pressure gauge and then to the red-blue-blue quick coupling. The yellow hose connects to the tank valve or vacuum pump. The three colors are for easy identification: red for high pressure, blue for low pressure, and yellow for refrigerant cylinders. 2. Nylon Resin Adhesive Tube: The 3 x 0.9m nylon resin adhesive tube is corrosion-resistant, liquid-impermeable, and high-pressure resistant, ensuring durability and a good seal. The maximum working pressure is 500 PSI. 3. Corrosion Resistance and Accurate Measurement: The 3-way diagnostic refrigerant charging pressure gauge set is durable and corrosion-resistant. Built-in calibration screws and vibration-damping indicators ensure accurate readings. 4. Blue and Red Low Pressure Gauges: The blue low pressure gauge has a measuring range of -30 inHg to 220 PSI, the red high pressure gauge from 0 to 500 PSI in degrees Celsius. 5. Easy-to-Read Dial: The easy-to-read 7cm dial features color-coded scales and a side mirror for better and easier monitoring of refrigerant levels and recovery. 6. Channels and Distribution Valve: The blue and red channels are always open. The low pressure distribution valve controls the connection of the blue and yellow lines, the high pressure distribution valve controls the connection of the red and yellow lines.
