Tracer Products' Cobra and Cobra-Plus borescopes feature built-in UV and white light LEDs that enable technicians to inspect and leak check hard-to-see components, such as pistons, intake valves, A/C evaporators, fuel systems, radiators, and evaporative emissions systems, without disassembly. The UV LED is suitable for detecting refrigerant leaks, fluid leaks, and surface flaws, while the white light LED works for component inspection. The TP-9350 Cobra features a 24-in (610-mm) shaft, and the TP-935036 Cobra-Plus offers an extra-long 36-in (915-mm) shaft for inspections requiring additional reach. A clip-on inspection mirror is included to detect flaws hidden from view. Fluorescence-enhancing glasses for use with UV light and fluorescent leak detection dyes also are included.
