Tellegloww AC Leak Detector Kit — 8‑Piece UV Dye & Manual Injector for R134a/R1234yf with 51‑LED UV Light

This compact service set combines a manual oil/dye injector, two low-side quick couplers, an R410 mini-split adapter, a sensitive electronic leak probe, a 51-LED UV flashlight, and protective glasses to help technicians and knowledgeable DIYers find and mark AC refrigerant leaks. Built from aluminum alloy, brass fittings, and impact-resistant components, the kit is designed for routine troubleshooting, pinpointing seepage, and introducing trace dye into cooling circuits.

How does the leak detector find tiny refrigerant leaks?

The electronic probe uses audible and visual feedback to help you locate escaping refrigerant: it beeps and flashes faster with higher leak rates. For visual confirmation, the included UV lamps illuminate dye in oil or refrigerant, making faint stains visible even in lit areas.

• Adjustable sensitivity on the electronic probe for small to large leaks
• 8.46-inch flexible probe for tight or hard-to-reach spaces
• 51-LED UV flashlight plus small UV lamp for clear dye illumination
• Protective glasses to improve dye visibility and shield eyes from UV

Can I inject oil or dye into different refrigerant systems?

Yes — the hand push injector accepts standard low-side connections and dispenses precise amounts of oil or fluorescent dye for R134a, R1234yf and other refrigerant systems. The injector’s aluminum body and 1/4" brass-style connectors resist wear and maintain a good seal.

• Manual 30ml (1oz) push injector for controlled dosing
• Universal 1/4" SAE-compatible quick couplers included
• Valve core remover for safe access to service ports
• Works with common UV leak detection dyes (dye sold separately)

What adapters and fittings are included for vehicle and HVAC use?

The kit arrives with low-side quick couplers for R134a and R1234yf plus an R410A mini-split adapter so you can service a wide range of automotive and residential systems without hunting for extra fittings. Brass and alloy construction helps ensure reliable connections under working pressure.

• R134a low-side quick coupler for most automotive A/C systems
• R1234yf low-side quick coupler for newer vehicle refrigerants
• R410A mini-split adapter for HVAC split systems
• Durable brass quick-connects and aluminum injector components

How easy is the kit to use and maintain?

Designed for straightforward operation, the injector screws into the low-side port and delivers dye by turning the handle; the leak probe reaches operating readiness within seconds. The textured grip and rugged materials make field use easier, while the rechargeable-free LED and UV lights simplify inspection without fragile bulbs.

• Leak detector warms up in about 6 seconds for rapid checks
• Textured grip helps control when hands are oily or greasy
• Battery-powered LED and UV lights (batteries not included)
• Impact-resistant aluminum body for shop durability

Who is this for: The Tellegloww kit is tailored for professional HVAC and automotive technicians who need a compact, multi-adapter diagnostic set, as well as experienced DIY mechanics who service their own AC systems. It’s ideal when you require a reliable manual dye injector, a sensitive electronic leak probe, and the right couplers to work across R134a, R1234yf and R410A equipment. Note: observe refrigerant handling regulations and use appropriate protective gear; dye and refrigerant cylinders are not included.
