TSI Supercool UV Leak Detection Dye, 1 oz, Orange Tint - 16525

Absolutely worked amazingly well. Found the leaky fuel injector seals on my 1986 4runner within a matter of a few minutes. Make sure you have a good ultraviolet light, did not even need the UV glasses. Highly recommend.

First time buyer of the UV diag stuff and works perfect. Made finding my leak super easy and quick.

Why did you pick this product vs others?:Good price for the buck.

One OZ to One Gallon.

This UV fluid leak detection dye quickly helped me locate an oil leak—it works exactly as advertised! However, the bottle leaked during shipping, which was disappointing. I tested it with two different wavelength glasses and found that the 90-490nm glasses worked much better for visibility. Overall, a great product for leak detection, but the packaging could use some improvement.

Find leaks fast. I used it in diesel fuel to see if fuel was leaking from the fuel filter cap. Found a small leak on an o ring on the housing and saved a customer some major money. Great deal. I will keep buying this stuff.

Delivered on time and to requested location. Contained items as specified.

This stuff is great made getting to the source of the oil leak alot easier, for best results use as directed and in very low light lights up under uv nice and bright. A must have in my tool box.
