## 1 Hose

 990

LeakArmor™ UV Dye is an advanced class of highly concentrated ultra violet dye that uses DRY R™ instead of POE oil as its carrier. As soon as it enters the system, the green dye quickly exposes leaks with the use of a UV light. It is ideal in locations where leaks are not easily spotted with conventional methods. The highly soluble fluid exposes all leaks, making them easy to find. 0.3 oz single use hose.
