Can accurately adjust the strain drop and may wisely distribute the The connector of the fuel for tank would be adjusted. Stable and dependable for valve strain leadership make sure your safety. Suitable for either home and car. Specification: Material: Metal, Rubber, Nylon Hose length: 110mm/4 hose length) Working Pressure: Burst Pressure: 4000 Connector of hose: 1/4'' SAE Refrigerant pressure gauge 0-120 Suggested 20-50 Color: As photo shown Quantity 1 Set Usage: 1. A air conditioner tube. 2. A bottle of R134A refrigerant 250 grams. 3. trying out the stress at the car: flip 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's a blue or black disguise on the left component of the hood, with an L on it, unscrew. 5. the automobile engine and turn at the air conditioner 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 to the low-voltage the strain gauge may have a scale indication in an instant. The hose is with the air con system. The strain gauge will reveal the stress within the system. 7. If the pressure within the air con formulas is low, the refrigerant needs to be replenished, the thimble in the bottle opener is circled clockwise, pierce the bottle mouth of the refrigerator, and the thimble within the bottle opener is immediately turned around 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 be taught the strain gauge scale, the place it is in step with the stress unit. 8. If the strain in the aircon formula is normal, rotate the thimble within the bottle opener clockwise to the lower end straight and tighten it to move the low port connector of the air con system. 9. If a bottle is rarely satisfactory after the addition, please upload the second bottle of refrigerant as described above till the outside temperature is in step with the formulas pressure. Note: Please allow 0-1cm error because of handbook measurement. pls make sure you do not intellect earlier than you bid.
