Robinair 16240 UV Dye Cartridge 237ml for HVAC/R Leak Detection

Robinair 16240 UV Fluorescent Dye Cartridge — 237ml | Refrigerant Leak Detection

The Robinair 16240 is a 237ml UV fluorescent dye cartridge designed for refrigerant leak detection in HVAC/R and automotive AC systems. UV dye is injected into the refrigerant circuit, the system is operated to circulate the dye, and a UV light is then used to scan components, joints, and fittings for dye seeping from leak points. The dye fluoresces brightly under UV light, making even small or slow leaks visible.

The 16240 is OEM-backed and meets SAE J2297 standard for R134a and R1234yf applications. Confirm compatibility with your specific refrigerant and system before use.

Important: Refrigerant system work including dye injection requires appropriate trade qualifications. Confirm licensing and compliance requirements with the relevant authority in your state or territory before undertaking refrigerant work. UV dye use may affect manufacturer warranty on some systems — confirm with the system manufacturer before injecting dye.

Key Features

• 237ml UV fluorescent dye cartridge
• OEM-backed formulation — meets SAE J2297 standard
• Compatible with R134a and R1234yf (confirm additional refrigerant compatibility against Robinair datasheet)
• Pre-measured application — 1/8 oz per charge
• Brightest dyes in the Robinair range for clear UV visibility
• Designed for use with a compatible UV dye injection gun

How UV Dye Leak Detection Works

UV dye is injected into the refrigerant circuit using a dye injector gun. The system is run to circulate the dye through the circuit. A UV light — such as the Robinair 5550AU UV work light — is then used to scan all components, joints, fittings, and connections. Dye seeping from leak points fluoresces brightly under UV light, pinpointing the source. This method is particularly effective for slow or intermittent leaks that electronic detectors may not consistently trigger on.

Best For

• HVAC/R technicians using UV dye as part of a refrigerant leak detection process
• Slow or intermittent leak detection where electronic detectors are inconclusive
• R134a and R1234yf system applications (confirm additional refrigerant compatibility)
• Technicians who prefer Robinair-branded consumables

Check Before Ordering

• Confirm refrigerant compatibility against the Robinair 16240 datasheet before use
• UV dye use may affect manufacturer warranty on some systems — confirm with the system manufacturer before injecting dye
• A compatible UV dye injection gun is required — confirm you have the correct injector before ordering
• A UV light is required to detect the dye — see the Robinair 5550AU UV work light
• Refrigerant system work requires appropriate trade qualifications — confirm licensing requirements in your state or territory
• Confirm warranty terms with HVAC Trade Supply at time of purchase

Frequently Asked Questions

What refrigerants is the Robinair 16240 compatible with?

The 16240 meets SAE J2297 for R134a and R1234yf. Confirm compatibility with other refrigerants against the Robinair manufacturer’s current datasheet before ordering.

Do I need a special injector gun to use the 16240?

Yes — UV dye requires a compatible injection gun to introduce the dye into the refrigerant circuit. Confirm the correct injector for the 16240 with HVAC Trade Supply or the Robinair datasheet before ordering. The Robinair 16234 UV Leak Detection Kit includes an injection gun.

Will UV dye affect my system or warranty?

UV dye use may affect manufacturer warranty on some systems. Confirm with the system manufacturer before injecting dye. Use only dye formulations compatible with your refrigerant and system.

Do I need a UV light to detect the dye?

Yes — a UV light is required to make the fluorescent dye visible. See the Robinair 5550AU UV work light or contact our team for compatible UV light options.

What is the warranty?

Confirm current warranty and returns terms with HVAC Trade Supply at time of purchase.
