ERRECOM Extreme – 30 ml, Leak Stop for Vehicle A/C Systems using R134a Refrigerant Gas, includes Adapter for Low-Pressure Charging Port R134a

I had an AC leak on my car, eventhough I have already purchased the replacement parts, finding time to take the car in for repair was hard. I came across this on Amazon and thought I'd give it a try, had nothing to loose. I can quite happily say that it's been approximately 7 weeks since I put this solution into my AC and topped up with gas and my AC is still freezing cold

For £20+ I would expect instructions! Yes I can go on YouTube, the issue with that is its full of clueless "wanabees". If your system is fully charged you will not be able to press the plunger, in fact because the fitting doesn't appear to have a one way valve you will have a lethal projectile from the back pressure. No gas in the system and the compressor will not kick in so running the engine for 30 mins will just add further expense and achieve nothing. Having instructions would prevent any mishaps, ideally I guess a half charged ac system would be best. All that said, and little common sense, my system was fully charged and the condenser leak minor.....I attached a G clamp to my syringe to prevent back pressure and slowly closed it (I couldn't have done it with my hands). Why 5 stars? Because the results were excellent, just give some thought to the above before going 'gung ho' potentially covering your engine bay in blue dye or worse still taking your eye out. Excellent stuff for condenser pin holes.

Didn't work for me, firstly the connector would not stay attached to the port of my a/c. I managed to get it into my fully gassed system via a different method and ran car for 30 mins immediately after putting it in. Its been in approximately 4 weeks and system is once again low and needs regassing. So I won't recommend as it didn't work for me.

Works well. Does it's job

Lots of bad and thoroughly misleading comments on here by people who have not used the product properly. Add to a pressurised/full/gassed system (ignore silly comments about the system having to be vacuumed/empty). Start car and run aircon on maximum Cold. Remove product from the box. Attach the adapter kit. Locate your low pressure port. Place the end the adapter on the low pressure port and push down the block collar to lock it on. Press (hard) on the plunger to inject the solution. When all in and whilst still holding down the plunger, pull up the black collar to release the connection. Keep car running for a while or better still immediately take it for a run to spread the solution through the system. Job done. How simple was that? - not simple enough for some it would seem….

Didn't stop the leak

This is a great product and well worth the money. But Note: 1) It is ONLY for small leaks (i.e. if AC loses gas over a few months Rather than a few days) 2) You MUST connect it correctly, otherwise as others have said it will simply leak all over the place You must turn you car on, set the AC to lowest temp, then inject the solution. Injecting can be difficult because of the pressure in the AC system. So wear gloves and press the white connector down very firmly before sliding down the black locking loop. TIP: Inject a small amount and check for leaks, if no blue solution is seen, then depress plunger fully. Car must then be left to run for 30mins to allow solution to fully circulate in system.

Won’t know if works until end of summer as slow leak Info on putting into system As directions ;fit adapter to low pressure of a/c,start car ,put on aircon to coldest with fan Now screw adapter to fluid syringe and screw onto adapter on aircon valve I first thought this wasn’t correct as couldn’t push down on syringe Note it needs a lot of pressure on syringe to push open valve So after really pushing on it all fluid went into system See if works in time Hope may help someone as hard to first see why fluid wouldn’t go in

Heb het gebruikt in mijn citroën ds3 vanwege een lekke verdamper, waardoor het aircogas na zo'n drie weken weggelekt was. Dit product heeft voor mij helaas niet geholpen. Airco wordt niet meer koud. Kan zijn dat het met een kleiner lek wel zou werken.

Ottimo prodotto problema risolto adatto alle micro perdite grazie

I had a small leakage in the condensor. I filled it month ago. Seems to be working. Easy to use with the included kit.

Hat super funktionert

Muy buen producto sello mi microfuga y mi aire acondicionado vuelve a funcionar como antes
