R134A Car AC Refrigerant Charge Hose Kit, Recharge Hose with Gauge Recharge Measuring Kit for Car Air Conditioning Low Pressure Port DIY Refilling Repair Tool

Product Description:This R134a refrigerant recharge kit includes hose with gauge, bottle opener, and adjustable connector. Thickened hose wall with brass fittings. For auto AC low pressure port recharging. Works with 250g refrigerant cans.Specification:Item Type: Refrigerant Recharge KitMaterial: Brass + HoseColor: As picture shownUsage:1. A refrigerant refueling tube for automobile air conditioner.2. One bottle of 250g R134A refrigerant.3. Now start to test the pressure of the car: first, turn the thimble counterclockwise in the bottle opener end of DIY supplementary pipe to the top, screw the refrigerant bottle into the bottle opener and tighten it.4. Check the low-pressure interface. Generally, there is a small blue or black hat at the left end under the hood.5. Start the car engine and turn on the AC switch of the air conditioner. Turn on the blower to the maximum.6. When the DIY pipe is connected to the low-pressure interface, the pressure gauge of the DIY pipe will instantly have a scale indication. At this moment DIY tube and air conditioning system are connected, see the pressure scale on pressure gauge, know the pressure in the system, add note below what pressure?Here is a knowledge statement!The pressure in the automobile air conditioning system changes according to the ambient temperature.In the following figure, the comparison table of Fahrenheit temperature and air conditioning system pressure confirms the high and low pressure in the system. The high system pressure indicates that the refrigerant in the system is more than the normal value, otherwise, the refrigerant should be supplemented.If the outside temperature is 30 degrees, the pressure in the air conditioning system should be 45PS!

• Complete R134a Refill Set: This refrigerant recharge kit includes a charging hose, pressure gauge, bottle opener, and adjustable low pressure connector. All components work together to refill your car AC system. No need to buy separate parts. The brass fittings have clear threads for a tight seal. For DIY automotive use only.
• Thickened Durable Hose: The hose features a thickened wall construction that resists kinking and bursting under pressure. Brass metal joints on both ends provide a secure connection to the refrigerant can and vehicle low pressure port. The quality materials ensure multiple seasons of use without cracking or leaking.
• Easy DIY Installation: Simple process requires no complicated tools. Attach the bottle opener to the refrigerant can, connect the gauge hose, then attach to the low pressure port under the hood. Start the engine and AC, then read the gauge. Complete instructions included. Compare ambient temperature to proper PSI. Helps diagnose low refrigerant.
• Universal Adjustable Connector: The low pressure connector fits most R134a service ports on US, Asian, and European vehicles. The adjustable design ensures a solid grip without damaging the port. Use the included pressure gauge to monitor system pressure while adding refrigerant. Gauge readings correspond to ambient temperature chart provided.
• Step By Step Refill Guidance: The kit comes with detailed temperature to pressure reference table. For example at 85°F system pressure should be 40-50 PSI. If lower, add refrigerant by puncturing the can and gently shaking. Stop when gauge reaches correct range. Includes instructions for one or multiple cans. Stable performance for multiple recharges.
