Frequently asked questions from our customers

Why does my circuit lose gas every time?

With age, vibrations often cause joints to leak. This is the main cause of loss of refrigerants but other anomalies can occur on the circuit causing a technical failure such as acidity in the oil, poor cooling at the condenser level, a problem with the compressor valves, electronic problem, regulation, etc.

• Is your TF134 gas the same as R134a gas? Yes
• My car already contains R134a, is it possible to add TF134 as a supplement? Yes, no worries.
• How many cans do I need to charge my vehicle? In principle one but in some cases two cans are necessary.
• Is a vacuum draw required? No, a vacuum is necessary when air has entered the circuit.
• Do I need to add oil when refilling? Not necessarily, our can contains a small amount (checking is advised).
• I added the refrigerant but I still can't reach the right pressures: several possibilities, please contact us.
• How do I know when my circuit is fully charged? It's very easy, our hose has charge and color indicators.
• I recharged but my circuit does not work correctly: Several possible anomalies, do not hesitate to contact our technical support.
• I recharged my circuit but the pressure is still at 0: Major leak in the circuit most likely but to be checked...
• In the event that I inject too much gas by mistake, is my circuit protected? Yes by HP security but to be avoided (degradation of the oil).
• Is it mandatory to put on a leak stopper before recharging? It is advisable to add a sealer but not mandatory.
• Which hose should I connect the hose to: Low pressure side, on the larger hose.
• Is your hose compatible on all vehicles? Yes for all R134a vehicles except in very special cases.
• How to refill with the hose? It's very simple, the filling is done by a tap, contact us if you need our technical help.
• What is the difference between TF134 and Duracool 12a gas? None, the products have +or- the same characteristics.
• I already have Duracool or other fluid in my circuit, is it possible to add TF134? Yes, no worries.
• I have a Duracool 12a compatible hose, can I connect it to TF134 cans: Yes, no worries.
• Can I remove R134a and inject TF134? Yes, provided you are authorized (ADC) and respect the recovery procedures, etc...
• My circuit runs on R1234Yf, is TF134 compatible? No, we have an equivalent product with flexible in our spaces.
• Is TF134 fluid hazardous to my health? Like any chemical, it must be handled with care.
