Stop-leaks extreme air conditioning system refrigerant R134A and HFO1234yf - syringe 30ml
Description
The SMB Auto Extreme Stop-Leak has been specially developed for all automotive air-conditioning systems using old-generation R134A (vehicles before 2013) and new-generation HFO1234yf (vehicles after 2013) refrigerants thanks to the 2 adapters included. It provides curative or preventive solutions to all micro-leakage problems in refrigerant gas circuits .
It locates leaks up to 0.5mm in diameter and seals them permanently without reacting with moisture and oxygen, saving you costly repairs (parts and/or labor).
Advantages :
- Universal dosage (1 x 30ml syringe per circuit).
- Ideal for preventive application.
- Permanently seals leaks in rubber and metal parts of air-conditioning systems.
- Compatible with all refrigerant gases (including CFCs, HFCs and HCFCs).
- Contains no polymers (no risk to the compressor).
- Does not react with humidity or oxygen.
- Detectable under UV lamp (tracer function).
- Significantly reduces compressor noise.
- Does not damage the compressor.
- Does not damage A/C system components.
- Does not damage recovery station components during gas refills.
Pre-check (optional):
- Locate the A/C system's low-pressure valve and unscrew its cap.
- Connect a vacuum pump and evacuate the A/C system for 5 minutes.
- Check the vacuum value obtained with a manometer.
- Stop the vacuum pump and check on the manometer that this vacuum value can be maintained for at least 4 minutes.
- If this is not possible, the leak is too large to be repaired with the Leak Stop device.
A simple check can also be carried out easily using the BARDHAL pressure tester (part no. TB15140 sold separately).
Instructions for use:
- Start the air-conditioning system and let it run at full power.
- Unscrew the syringe cap and connect the black or green adapter to the low-pressure valve (the black connector is for circuits equipped with R134A gas, the green connector is for circuits equipped with HFO1234yf gas).
- Insert the leak-stop by pressing down on the syringe plunger.
- Disconnect the fitting and syringe from the low-pressure valve.
- Replace the cap on the low-pressure valve.
- Allow the system to run for at least 30 minutes.
Please observe all safety precautions.
