Certified A/C Pro Car Air Conditioner Leak Detector Dye, Leak Detection UV Dye Detects Leaks in R-12 and R-134A Air Condition Systems, 1 Oz, InterDynamics

Good price for this works well. Great brand

This stuff works! I was able to quickly identify the source of the leak. It shines very brightly under a UV light.

Big fan. I have used this product for a while and easy to use. My only critisism is the included directions. To be honest, they suck. A 1oz. bottle contains four treatments. I can tell you there are basically three ways to use it. If you are working on an A/C system that has no dye then inject 0.25 oz. into the system. If you are working on a vehicle that does not have UV dye added and are replacing a component (such as the compressor or condensor). Either add 0.25oz of dye directly into the new part, before installing it or mix 0.25oz. of dye to 8oz. of PAG 46 and inject the recommended amount of oil to the system, after the repairs are completed. If the manufacturer has already added dye to the A/C system and you are performing a repair or refill service, mix 0.25oz of dye to 12oz. of PAG 46.

Not sure if it’s a common issue but one of the bottles I ordered (1 of 2) ended up leaking during transit but other than that all good

This dye works as its supposed to.

Lo compré para revisar una posible fuga en el aire acondicionado del carro y cumplió su función. Es fácil de usar y el colorante ayuda a identificar rápido por dónde está el problema. No soy experto y aún así pude usarlo sin complicaciones. Muy útil para detectar fugas antes de gastar dinero de más en el mecánico.

Great way to find leaks! I dumped it into the bottle of clear oil I was using, versus adding it on it's own to the AC system. I was changing the dryer, so I'd need a few ounces of oil anyway. Now I've got a big bottle of oil with dye ready for any future work. It lights up bright green under a blacklight. You can't miss it.

The UV dye seems like a good product. However, the packaging is not tamper evident. The first bottle was leaking out of the package when it arrive. I ordered a replacement and it was opened already. Leaking UV dye is never a great surprise.

El producto cumple su función. Completamente recomendado.

Didn’t get to use it. But it’s pretty straightforward. You need a UV light to detect this leaking from your ac system.

Good brand but, it was useless for me i couldnt use the product because it's not compatible with AC charging kit's fitting.

very good

This product when used with a uv light, ac leakage will appear as a white spot. Great maintenance support for ac leakages. Add to any ac system, will no damage pump or hoses.
