Robinair 16240 UV Dye Cartridge 237ml

The Robinair 16240 is a 237ml UV dye cartridge designed for refrigerant leak detection in HVAC, refrigeration, and automotive air conditioning systems. Inject UV dye into the refrigerant circuit, run the system, then scan with a UV light to pinpoint the exact source of the leak — even in hard-to-see locations.

Key Features

• Volume: 237ml (8 oz) cartridge
• Compatible with: Robinair UV dye injection systems
• Application: Refrigerant circuit leak detection via UV fluorescence
• Suitable for: HVAC split systems, ducted systems, refrigeration circuits, and automotive AC

How UV Dye Leak Detection Works

UV dye is injected into the refrigerant circuit and circulates with the refrigerant. When a leak is present, dye escapes with the refrigerant and fluoresces brightly under UV light, making the leak source immediately visible. This method is particularly effective for slow leaks that are difficult to detect with electronic detectors alone.
