Refrigeration Technologies RT100S Big Blu Micro Leak Detector 1 Qt Viper

This is the good stuff. I use it on HVAC, car tires, hoses, etc. It stays put and makes finding leaks easy. The bottle could be better designed, it is very slow, but it holds up.

This stuff works great!

I had my new mini-split system vacuumed down, 3-stage pressure leak test and they apparently didn't follow the makers instructions which clearly note the high pressure test is necessary, yes it is This system worked perfectly for a few months then the cooling performance stated to diminish. After a year catting the AC service company and the makers tech support I decided to complete the high pressure test myself After 2 hours into the 3rd and finally 550 psi test, the ac psi gauge didn't move. However using this wonderful spray I detected a small slow leak and a micro leak. Now I'll inform the AC company and the maker. The trouble-shooting with the makers tech support failed to suggest to check the systems refrigerant psi simply because there wasn't an error code. A waisted year with no cooling or heating. This is a great product and it does cling to the copper lines extremely well over a period of time M

Great product. Shipping issue with leaking bottle, a cardboard mess; seems like a simple plastic bag would be helpful.

I love this stuff. Works exactly as it’s meant too. Big bubbles quickly when there is a leak

Can beat the thickness of bubble solution. Way better than dawn and water

Works

Big Blue Leal Detector seems to be the best on the market`!
