Leak Detector Blue Refill Bottle - Fast Acting, All-Purpose Leak Detection for High & Low Temperature Applications in Gas & C02 Systems (1 Gallon)

Don't use often, but works as it should and seems to be good quality

Works just like it should!

This product seems to do the job, however, the spray bottle it comes in is useless and leaks all over my hand when I try to spray. I transferred the contents to a better quality sprayer and it now works great.What a shame this company lets its product down by using a low quality spray bottle.

Good product. Works as advertised. Would purchase again.

Worked very well in finding gas leaks in my HVAC natural gas lines.

I tried soapy water I tried just soap. I tried big blue. Finally I over inflated my 20 foot RHIB and sprayed it in sections. Voila. A little tiny llean near the bottom started bubbling. I could have jumped for joy after spending a week trying to find that micro leak.The leak was so small that once the presser started getting low I couldn’t see the leak. So make sure to over inflate to find the leak.

I installed a ridetech air suspension on my car and had a slow leak that I could not find with soapy water. Withing seconds of applying this product I found the leak.

The sprayer goes from nothing, to a full messy squirt, there is no slow spray option. It makes a big mess. Also I found that it dries fast so it is not suitable for a slow leak. I was unhappy with this product, I had high hopes after reading glowing reviews.
