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

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.

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 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

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

Top tips 1) Screw the syringe onto the adapter before fixing to the low pressure port. If you don’t you may lose the AC refrigerant gas already in the system 2) For those who say they can’t press the solution into the AC low side as it’s too hard….. get someone to sit in the drivers seat and raise the revs to around 2.5k rpm. As the revs are raised, press (hard) the syringe. If it’s still too hard to inject, then raise the revs. The higher the revs, the more it assists in inserting the fluid (think of higher revs as higher suction as the fluid is inserted) Hopefully this helps.

We had a small leak in the car ac system, garages said they couldn't find it. The ac would last two or three weeks max gradually reducing in efficiency and then stop due to insufficient gas pressure. I resorted to topping up DIY with gas and so called leak stop numerous times, (mainly so we could travelel with the dog in the car), it never worked and cost me a fortune. Since using ERRECOM Extreme leak stop over a month ago, the ac has been working 100% no descernable deteriation. So looking likely it's done the trick. Which I knew about this stuff before I spent £100s on DIY cans and filling equipment. Watch this space I will update in a couple of months.

Great product, easy to use, some reviews saying system shouldn't has gas in it but that's nonsense how else is the product meant to work? Start engine , turn ait con on fully and clip on the adaptor to low point adaptor self seals so there's no gas leak, then inject the product, yes it's had as you are pushing against the gas pressure. Total job took 2 mins. I dont know it my leak is small enough to be fixed but the product is easy to use.

Recomendado. Después de aplicarlo no he vuelto a tener fuga de gas y ya ha pasado un mes

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.

Funziona…Pienamente soddisfatto

Bis jetzt muss ich 5 Sterne geben, ich habe es eingefüllt, das ist fast 5 Wochen her, bis jetzt funktioniert es perfekt vorher war nach 4 Wochen Schluss, musste erst wieder nachgefüllt werden. Werde es beobachten und aktualisiere es dann👍😄 es sind jetzt 9 Wochen her, funktioniert immer noch perfekt 👍

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