RT175B Big Blu Brush On MicroLeak Detector Blue

This is not your typical soapy water. This is some thick stuff. Normally I use soapy water or some type of cleaner and wanted something more sensitive. While this takes a little time for stuff to show, this is quite good at showing the micro leaks. I’m very pleased at this for the price as this helps finding a tiny leak when a leak detector can’t find it when it’s a little breezy.

Great product that everyone should have around for checking for possible leaks

Best leak detection that I have used. You will know one way or the other if you have a leak. Simple and trustworthy.

Does what you'd expect. Helped me find a really small leak in a welding setup. A little goes a long way.

The product is easy to apply and great at finding leaks. Shows small leaks you just cannot find using home made soapy water. As reported by others the product leaked in shipping, but I only lost a small amount. You should considering purchasing from local store, if available in your area.

It works great !!! Its easier to use than the spray. you can put it right on the joints without wasting

I have tested a lot of pressure joints in my day and this is just way easier than mixing soapy water. You get everything you need and can close it up for next time. Maybe I'm getting lazy later in life but I'm not going back to the old way. This blows bubbles perfectly and this bottle will last me a long time.

Works good for air conditioning lines. For checking leaks
