R410 22 134A Air Conditioning Pressure Gauge, 3-Way, Diagnostic AC Manifold Gauge Tube Assembly for Freon Charging

1. Connection: Each end is equipped with a 1/4" internal brass threaded fitting for easy connection. The red hose connects to the 1/4" external red threaded end of the gauge to the red, blue-to-blue quick-connect fitting, and the yellow hose connects to the tank valve or vacuum pump. Three colors are easy to identify: red indicates high pressure, blue indicates low pressure, and yellow indicates refrigerant cylinders. 2. Nylon resin adhesive hose: Adopting a 3x0.9m nylon resin adhesive hose, it is corrosion-resistant, with low fluid resistance and high pressure resistance, ensuring durability and good sealing performance. The maximum working pressure is 500 PSI. 3. Corrosion Resistance and Precise Measurement: The AC 3-way diagnostic gauge set for refrigerant charging is durable and corrosion-resistant. Integrated calibration screws and anti-vibration pointers ensure accurate measurements. 4. Blue and Red Low Pressure Gauges: The blue low pressure gauge has a range of -30 inHg to 220 PSI, and the red high pressure gauge has a range of 0 to 500 PSI in degrees Celsius. 5. Easy-to-Read Dial: The easy-to-read 7 cm dial features color-coded scales and an observation mirror on the side panel for better and easier monitoring of refrigerant charging and recovery. 6. Channels and Manifold Valve: The blue and red channels are always open. The low-pressure manifold valve controls the connection of the blue and yellow wires, and the high-pressure manifold valve controls the connection of the red and yellow wires.
