There is no better solution than OEM’s detector that can find out gas leakages faster. It is commonly used in HVAC, plumbing, telecom, aerospace, gas utilities, service industries and MVAC. This is a strong and persistent film forming liquid, capable of detecting micro gas leakages effectively. Industries that use pressurized gas systems can make use of this advanced propriety formulation. Currently, it is one of the most popular products used by many service technicians throughout the US, Canada, Japan and the Pacific Rim.

This refrigerant leak detectant coated, and remained in place, even when sprayed on vertical pipe. The bubbles, that are created from a refrigerant leak, do not pop. It will create a mass of bubbles that continue to collect on the location of the leak. I’ve used off brands, and other manufacturers. Yet, in my personal opinion, this product works more efficiently, and clings to surfaces, better than the competition.

No bubbles unless you have a leak. Bubbles when you do. This stuff works great. I did however receive a bottle that had the top unscrewed. The liquid was mostly contained in a plastic bag tied around the bottle, but about a third had escaped. Amazon got a new one on the way immediately. It arrived undamaged.

This leak detection solution is pretty good at finding leaks. The spray bottle it comes in is not good though. I would recommend the solution but maybe get another sprayer for it

Edit: this product leaves an oily residue behind. Oil is the easiest way to detect leaks visually first. Learn how to find leaks without it, and when you need this, it'll save your neck. But, if you're new, and can't find the leak, don't use it and ruin the experienced technician's attempt when he comes in after you.This is a thick solution that will hold on to the sides of vertical pipes. I was a helper for a senior technician out in the field on a brazing call. He charged the system with nitrogen, used some soap and water on a recent braze, found nothing, and I come in with this product. He got a little bent about the fact that I wanted to double-check his work, but he couldn't really say anything when this one found a leak that he couldn't see.

I bought this for some work on an AC system. Soon after I found myself with a leaking tire. With this spray only a few minutes were required to find the leak (a very short self-tapping screw hidden in the tire tread).A few sprays and the bubble appeared rapidly.Looking forward to use on various systems.

Initially I tried the swab version of this product and was disappointed. After talking with a refrigeration tech at work he recommended the spray application. By gently spraying it prevents unnecessary bubbles where you are leak checking. Any leaks are quite obvious.
