TSI Supercool 28399 Hvac Leak Stop Syringe With Application Hose, 2 Fl. Oz. (60 Ml)

Worked out to my car AC. All the gas leaked within a week. Refilled the gas and is successfully cooling.. one more problem faces is connector didn't work out so opened the cap of tube and directly applied

Does not seal the leak

Very good products and very effective

Good product

The connecter included does not fit a car AC port. The syringe is weak and does not offer much leverage to inject the liquid; I used an adaptor but still, the liquid did not go through.

I purchased this one for minor gas leak and it did NOTHING!!! don't waste your money

not good

Long story short, this product is so much easier to inject using an HVAC dye injector. A nice metal one is available for $30 on Amazon. I have no idea why it doesn't ship with one or that the manufacturer doesn't recommend it. They really should! The syringe it comes with sits near the edge of structural failure and needs modifications to even work! Short story long, my uncle fixes people's HVAC on the side for cheap. He swears by this stuff as the first response to slow leaks. However, the directions/videos on how to use this product are a joke. They show technicians just injecting the stuff easily and quickly in 30 seconds. This is not going to happen if you use the syringe. The pressure inside an R410a system is near 150 PSI. For me to use the syringe, I had to first stop the plunger from bending by sticking pieces of extra plastic around it so it would not bend. I had to use a washer on the front to stop the caulk gun from destroying the syringe front. Then I needed an extra clamp to help close and hold the caulk gun handle. Even then, I could only inject about a hair's width worth every 5 minutes. If I clamped it and let it sit, the system would eventually pull some out of the syringe, and I could repeat this. Before I could get this to work, the check valves were both locked up. I had to extend the Schrader valve trigger on the front valve and poke out the rear check valve because the tubing had excessive pressure that had them locked up. This was extremely dangerous. When it release it sounded like a gunshot and sent the Allen wrench I poked it with flying out of sight. I nearly got a hydraulic injection wound from a stream of this blue stuff! Do not try this! Once I was able to get the blue stuff flowing again, the issue was that the syringe would always come loose because it only needs one turn to start leaking, so about 3/4 of the product ended up on the ground as I messed with it. I ordered another tube because they are only $20. I also ordered a metal HVAC dye injector for $32 off Amazon. It just opened it all the way, squirted the blue stuff in, closed it, and bled out the air until blue came out the tube end. I connected it and turned it a half turn every 10-15 seconds until it was empty. So much easier, no waste, and much safer! Please just spend the extra money to inject this, especially if it has a chance of working. $55 is much cheaper than $500 or $5000.

عندي مكيف اعبية فريون مرتين في الصيف. فنيي التبريد مايبون يشتغلون لذلك شريت هالابره ورحت محل قطع غيار تبريد واخذت فريون وساعه وكذلك محول لان اللي اللي معه حجم صغير والفريون الجديد اكبر. المهم استعنت بمسدس السيليكون لاضغط المادة في المكيف وبعدها عبيت الفريون. والحمد لله الحين 4 شهور والمكيف بارد وممتاز. اتوقع اللي مايمدحونه يا انهم ماعرفوا يضيفونه او التهريب قوي

Did not fix even a tiny leak.

I was getting ready to sell my house and had just replaced the downstairs outside A/C unit. $3000. 2 weeks before sale, I got a leak in my HVAC. Had an HVAC tech come out and service it, he thought it just needed freon. Took less than 2 days for all that to leak out and downstairs ceased cooling again. Had him come out again and he said it would be another $3000 to replace the HVAC. I wasn't trying to pay 3 grand so the next owners of my house could be super comfortable so I searched and found this product. Followed the directions to a tee and within a few hours, the downstairs unit was holding steady at 69 degrees and is still working fine to this day according to the new owners. Total lifesaver and easy on the wallet.

تم تركيبها و قد احتاج لمدة طويلة حتى اعرف اذا تعمل او لا لكن حتى لو عملت جيدا لن انصح بها لأن استخدامها صعب للغاية بسبب الحاجة لدفع قوي و حتى اذا استخدمت مسدس السيليكون سوف تنكسر لذلك انصح باستخدام اليد فقط و التنفيذ بحذر شديد ايضا يجب الا يكون المكيف ممتلئ بالغاز لكي يصبح دفع المادة اسهل قليلا
