new and high quality OOTDTY  Features: Made of high quality material, durable, high pressure resistant and reliability. Used to check the low pressure side's pressure and add R134A refrigerant to high performance vehicles or home air conditioners. High sensitivity, simple for valve debugging, safe and reliable, serve you for a long for time. With a built-in safety clicket to prevent accidental leakage of refrigerant. Can accurately adjust the pressure drop and can properly distribute the The connector of the gas for tank can be adjusted. Stable and reliable for valve pressure control ensure your safety. Suitable for both home and car.

Specification: Material: Metal, Rubber, Nylon Hose length: 110mm/4.33in hose length) Working Pressure: PSI Burst Pressure: 4000 PSI Connector of hose: 1/4'' SAE Refrigerant pressure gauge 0-120 PSI Suggested 20-50 PSI Color: As picture shown Quantity 1 Set

Usage: 1. A air conditioner tube. 2. A bottle of R134A refrigerant 250 grams. 3. start testing the pressure on the car: turn the thimble in the end of the tube opener counterclockwise to the top, screw the refrigerant bottle into the bottle opener and tighten. 4, Find the low-pressure generally there is a blue or black cover on the left side of the hood, with an L on it, unscrew. 5. Start the car engine and turn on the air conditioner AC switch. The blower is opened to the maximum. Wait for three minutes and the hose to the low-pressure end of the car air conditioner. 6. After the hose is connected to the low-voltage the pressure gauge will have a scale indication in an The hose is with the air conditioning system. The pressure gauge will show the pressure in the system. 7. If the pressure in the air conditioning system is low, the refrigerant needs to be replenished, the thimble in the bottle opener is rotated clockwise, pierce the bottle mouth of the refrigerator, and the thimble in the bottle opener is immediately rotated counterclockwise to the top to the refrigerant bottle. Up and down inversion, gently shake the refrigerant bottle, the refrigerant liquid will into the system, and look at the pressure gauge scale, where it is consistent with the pressure PSI unit. 8. If the pressure in the air conditioning system is normal, rotate the thimble in the bottle opener clockwise to the lower end immediately and tighten it to move the low port connector of the air conditioning system. 9. If a bottle is not enough after the addition, please add the second bottle of refrigerant as described above until the outside temperature is consistent with the system pressure.

Note: Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid. Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!
