Tellegloww AC Leak Detector Kit — R134a/R410A UV Dye & Electronic Sniffer with 68‑LED UV Light

Tellegloww AC Leak Detector Kit combines an aluminum alloy dye injector, electronic refrigerant sniffer, UV flashlight, safety glasses and adapters to locate leaks in automotive and small HVAC systems using UV dye and audible detection.

This compact kit brings together tools technicians and DIYers need to find and confirm refrigerant leaks without expensive shop equipment. It supports common refrigerants (R22, R134a, R404a, R410A, R1234yf and most halogenated blends), includes quick-connect couplers for low side service ports, and supplies both a 68-LED UV flashlight for visual dye tracing and an electronic probe that signals escaping refrigerant.

How does the electronic leak detector identify escaping refrigerant?

The included electronic sniffer powers up quickly and alerts you with audible beeps and a flashing LED when it senses refrigerant vapors. You can adjust sensitivity before probing tight spots or follow the probe along suspected joints and hoses to pinpoint the source.

• Ready to operate in about six seconds after power-on
• Adjustable sensitivity helps on heavy or slow leaks
• Flexible ~8.46" probe reaches tight seams and fittings
• Audible and visual indicators increase with leak severity

How is UV dye used to confirm and visualize a leak?

The kit’s oil-based UV dye is injected into the low side service port using a sturdy aluminum alloy injector that threads onto 1/4" SAE-compatible connectors. After running the system to circulate the dye, the 68-LED UV flashlight makes the tracer glow at leak sites, while supplied wraparound safety glasses shield your eyes.

• Oil dye designed for automotive and small HVAC systems
• 68-LED UV flashlight highlights dye deposits under leaks
• Protective glasses with side coverage prevent stray UV exposure
• Valve core remover and adapters included for easy access

What fittings and adapters are included for different refrigerants?

The kit ships with multiple quick couplers and an R410 mini-split adapter so you can connect to R134a and R1234yf low-side ports as well as other common fittings. Brass quick connectors and robust components are built for repeated service and compatibility with SAE-style connections.

• R134a low-side quick coupler included
• R1234yf low-side quick coupler for newer vehicles
• R410 mini-split adapter for small-split systems
• 1/4" brass connectors and valve core remover for convenience

How easy is the kit to use and maintain?

Controls and ergonomics are tuned for field work: the injector handle has a textured grip for use with oily hands, and the leak detector’s probe is flexible for navigating cramped engine bays. Batteries are user-supplied (4 AAA for the injector dye unit and 6 AA for the UV flashlight), keeping replacement straightforward.

• Textured handle for reliable turning under slippery conditions
• Simple syringe-style dye injection—turn until desired amount dispenses
• Probe flexibility reduces need to disassemble components
• Consumables (batteries, dye) are easy to replace

Who is this kit for? Automotive technicians, HVAC contractors working on small systems, and informed DIYers who perform routine AC troubleshooting will find the Tellegloww AC Leak Detector Kit useful. It’s tailored for people who need a portable, multi-method approach—electronic sniffing plus UV confirmation—to diagnose leaks in passenger vehicles, mini-split units, and similar systems without investing in bench tools.
