Mastercool Leak Detection Tools Editorial Review

The MASTERCOOL 53351-B Professional UV Leak Detector Kit is an effective tool for finding leaks in various systems such as power-steering, oil, gas, and transmission.

However, several customers have reported issues with the UV light, stating that it is dim or does not emit UV range spectrum. The kit does come with glasses for protection and a dye injector. One common complaint is that there is not enough dye for the A/C system. Despite some flaws, the tool has received positive feedback for its effectiveness in leak detection.
