Changing environmental standards have introduced new refrigerants into automotive air conditioning systems, including 1234yf. For those who manage the maintenance of these modern air conditioners, this charging hose is the essential tool. It has been designed specifically to connect a can of substitute gas such as Duracool, Multicool or Climapure to your vehicle's 1234yf low pressure circuit. Its design ensures safe, accurate and efficient intervention, avoiding the need for complex or expensive equipment. It is the preferred solution for professionals and experienced individuals who are looking for reliability for compliant air conditioning recharging.
This charging hose incorporates a professional-grade manifold, designed to make it easy to monitor system pressure. The pressure gauge clearly displays an extended measurement range, from 0 to 200 psi. This indicator is strategically placed at the end of the hose for instant and convenient reading during handling. For Duracool, Climapure or Multicool refrigerants used as replacements, it is imperative to never exceed the maximum pressure of 45 psi when charging. Scrupulous adherence to this ideal zone not only ensures optimal air conditioning efficiency, but above all the protection of your compressor.
The main distinction of this product is its crimped fitting specifically adapted to systems using HFO-1234yf gas. Unlike R134a, 1234yf requires a single fitting for safety and compatibility reasons. This hose is equipped with the corresponding low-pressure quick coupling , ensuring a perfectly sealed and leak-free connection to the vehicle's service port. It is essential to emphasize that this hose is strictly reserved for 1234yf low pressure circuits. This specialization eliminates any risk of connection errors, ensuring full compliance with the technical specifications of the most recent vehicles.
In order to facilitate the injection of fluids, the device is equipped with a tap with a needle. This simple but essential mechanism allows the refrigerant can (Duracool, Multicool, Climapure) to be pierced safely. Once the can is pierced and the fitting attached to the vehicle, the valve allows precise control of the opening and closing of the gas flow. Flow control is a key factor in adjusting the load to the pressure of up to 45 psi and preventing your air conditioning system from being underfilled or overloaded.
Here are the recommended steps for optimal use:
Check system compatibility (only 1234YF low pressure).
Screw the Duracool /Multicool/Climapure bobbin onto the needle tap.
Connect the 1234YF low-pressure fitting to the vehicle.
Gently turn on the faucet while monitoring the pressure gauge.
Stop the load as soon as the needle reaches or approaches 45 psi.
With its hose length of 27 cm, this hose offers an excellent compromise between manoeuvrability and compactness. It is the ideal tool for working in the often cramped engine compartments of modern cars equipped with the 1234YF. The simplicity of the operation allows the user to recharge the air conditioning independently, with full knowledge of the facts. The pressure gauge is the central element of the process: it simplifies a task that may seem complex.
Application examples:
Recent Vehicles : To recharge the air conditioning of cars marketed since 2017 and using 1234yf gas.
Preventive Maintenance : To regularly check the pressure of your 1234yf air conditioning system and prevent a drop in performance.
Post-Service Recharge : Following a replacement of a part (such as a gasket or hose), to complete the charge in Duracool or Climapure.
Meeting the 45 psi limit is key to success for these surrogate fluids in a circuit designed for 1234yf.
