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

Worked well and easy to use

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 placeYou 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.

Hate buying stuff that doesn't work and this is in the top 2.. where do I start. The fact it doesn't connect to the aircon pipe is the first issue.. then the fact you think it does but just leaks all over your hands and into the bulk head.. not sure what car it does connect to as im guessing all connections are the sameSeriously give it a miss Guy's..

This should definitely be used in an un-pressurised system!! This nearly caught me out but I caught the plunger creeping out. Probably better to get a can of cool5 with repairing properties and save time..

Easy to use

Easy to use

On my car the system hold the gas only for 2 days so it have a small leak. I thought is going to work with this product but same as before lost all gas in 2 days. Easy to put in system if you vacuum it first

Terrible product, does not come with paper instructions and you NEED QR code just to some how find them. If you manage to find instructions they are entirely in Italian.Product said it was specifically for my car model but the connector does not fit on the lower pressure connector, which majority of cars in the UK low pressure connector are the same.
