Tellegloww AC Leak Detector Kit — R1234yf/R134a/R410a Leak Finder with UV Dye Injector, 68-LED UV Flashlight & Low-Side Couplers

Tellegloww AC Leak Detector Kit is a complete refrigerant leak testing and UV dye injection kit designed to find and visualize leaks in R1234yf, R134a, R410a and many halogenated refrigerant systems.

This all-in-one kit combines a durable aluminum alloy oil/dye injector, low-side quick couplers for R134a and R1234yf, an R410 mini-split adapter, a valve core remover, an electronic leak sniffer, a high-intensity 68-LED UV flashlight and UV protective glasses. It’s built to help technicians and DIYers trace leaks faster by both sensing escaping refrigerant and making leaks visible with fluorescent dye under UV light. Components are made from heavy-duty aluminum and brass for repeated field use.

How do I use the Tellegloww kit to find a refrigerant leak?

Start by attaching the correct low-side coupler (R134a or R1234yf) or the R410 adapter to the service port. Use the valve core remover and connect the injector syringe to introduce the measured UV dye or oil into the system, then run the system to circulate the dye. For electronic detection, power the leak detector, adjust sensitivity, and sweep the probe around fittings, hoses, and coils until the alarm and LED indicator signal.

• Attach correct coupler to low-side service port for safe connection.
• Inject dye via the aluminum alloy syringe until desired amount is set.
• Sweep the detector probe near potential leak areas; listen for alarm and watch LED flash.
• Illuminate suspect areas with the 68-LED UV flashlight while wearing supplied protective glasses.

What refrigerants and systems does this kit support?

The detector is compatible with a wide range of halogenated refrigerants including R22, R134a, R404A, R410A and newer HFO blends such as R1234yf. The included R134a and R1234yf low-side quick couplers plus the R410 mini-split adapter let you work on most automotive and light commercial systems. Materials and connectors are SAE-compatible, built from brass and aluminum for a reliable seal.

• Detects HFC, CFC, HCFC and many refrigerant blends including R1234yf.
• Includes R134a and R1234yf low-side quick couplers and R410 mini-split adapter.
• 1/4" SAE-compatible connectors and brass quick fittings for durable service.

How accurate and easy is the leak detector to operate?

The electronic leak sniffer warms up in about six seconds and lets you select sensitivity levels to match leak size. A flexible 8.46" probe helps reach confined spaces; the unit emits a faster alarm cadence and quicker LED flashing when leak rate increases. The textured handle and robust build make one-handed operation straightforward even with greasy hands.

• Detector ready in ~6 seconds with adjustable sensitivity settings.
• Flexible 8.46-inch probe for tight areas and directional searching.
• Audible alarm and LED flash rate scale with leak magnitude for quick triage.

What safety and protection features are included?

The kit includes UV protective glasses with extended side shields to block stray UVA illumination when inspecting dye-marked components. The mechanical parts use corrosion-resistant metals to reduce failure risk during service. For visual inspection, the powerful 68-LED UV flashlight reveals fluorescent dye traces without damaging surfaces when used properly with eye protection.

• UV safety glasses with extended side protection to reduce stray exposure.
• Durable aluminum alloy and brass components resist wear and corrosion.
• Separate UV flashlight and detector lamp provide visual dye confirmation.

Who is this for: The Tellegloww AC Leak Detector Kit is aimed at professional HVACR technicians, mobile auto AC specialists and experienced DIYers who need a portable, multi-refrigerant solution for diagnosing leaks. It’s useful for automotive A/C, mini-split and light commercial systems where both electronic detection and UV dye visualization speed up troubleshooting and repair preparation.
