[Compatible Refrigerants]
R134a, R22, R404A, R407C (suitable for most automotive and some home AC systems)

[Key Features]

• Dual gauges for simultaneous monitoring of high and low pressure sides, enabling accurate system diagnosis.

• Three durable hoses (red/blue/yellow) with standard fittings for flexible operation.

• Adjustable adapters fit various vehicle AC service ports.

• Can tap allows easy piercing of refrigerant cans; valve core wrench simplifies core removal/installation.

• O-rings ensure leak‑proof connections.

[Important Usage Notes]

1. Always wear protective gloves and goggles during operation.

2. This kit is intended for professional use or under the guidance of a qualified technician.

3. Always refer to the vehicle/equipment manufacturer's recommended pressure values – do not exceed them.

4. Do not pressurize above the high‑pressure gauge's maximum scale (800 psi) to avoid damage or hazard.

5. Do not use this gauge set as a pressure regulator.

6. Before each use, verify that the needles point to zero. If not, loosen the dial screws and adjust the calibration screw to reset to zero.

7. The yellow hose has no purge valve. To purge air, slightly loosen the connection, let refrigerant vapor escape, then retighten before opening the valve.

8. When using the adjustable quick‑coupler on the AC service port, stop turning once the gauge needle begins to move – over‑tightening can wear out the Schrader valve.
