Tellegloww AC Leak Detector Kit — R1234yf/R134a/R410a Dye Injector Set with UV Lamp, Quick Couplers & Probe

This all-in-one kit pairs a metal oil/dye injector and three service adapters with both audible electronic leak sensing and UV dye inspection tools so you can find refrigerant escapes faster. Built from aluminum alloy and brass connectors, the components support common refrigerants including R1234yf, R134a and R410a and are meant for routine maintenance, troubleshooting and pre-repair diagnosis.

How does the kit actually detect a refrigerant leak?

The electronic leak detector uses sensitive circuitry to sense escaping refrigerant vapors and signals leaks with sound and an LED indicator. For visual confirmation, the kit includes UV dye and two UV lamps plus protective glasses so dye-marked leakage points glow under black light.

• Electronic probe ready to use within seconds with adjustable sensitivity
• Audible tone and flashing LED that increase with leak size
• UV dye injector to dye the system oil for visual verification
• 28-LED UV flashlight and small inspection lamp for visual detection

Which system connections and refrigerants are supported?

The kit includes a selection of low-side couplers and an R410A mini-split adapter allowing service on many vehicle and HVAC systems. Materials and thread sizes are chosen for common service fittings so you can attach to SAE-type low-side ports and compatible manifolds.

• R134a and R1234yf low-side quick couplers for automotive systems
• R410A mini-split adapter for heat pump and ductless systems
• Brass quick connectors and 1/4" aluminum alloy injector body for durability
• Detects HFC refrigerants like R22, R134A, R404A, R410A and most mixtures

What’s included and how do you use the dye injector and detector safely?

The kit ships with a syringe-style oil/dye injector, valve core remover, protective UV glasses, a small UV lamp, a 28-LED UV flashlight, and three service adapters. To inject dye, connect the injector to the low-side, turn the handle to meter dye into the system; use the probe and UV light to inspect possible leak sites while wearing the supplied glasses.

• Syringe-style injector screws into the low-side port for controlled dye addition
• Valve core remover and adapters included for common service tasks
• Wear supplied UV protective glasses when using UV light or handling dye
• Adjust detector sensitivity and extend 8.46" flexible probe to reach tight spots

How durable and user-friendly are the tools for shop or DIY use?

Components are built from heavy-duty materials—aluminum alloy for the injector and brass for the quick connectors—so they withstand repeated service use. The injector handle has a textured grip for turning with oily hands, and the detector’s flexible probe and compact UV flashlight make inspections in cramped engine bays or indoor units easier.

• Rugged metal construction for repeated professional or DIY use
• Textured injector handle for secure turning even when greasy
• Flexible 8.46" probe reaches tight, hidden areas
• Battery-powered lamps and detector for portable inspections (batteries not included)

Who is this for: The Tellegloww AC Leak Detector Kit is suited to automotive technicians, HVAC service pros, and knowledgeable DIYers who work on vehicle air conditioning or mini-split systems and want a compact, combined electronic and UV dye method to find refrigerant leaks. It’s designed for troubleshooting, pre-repair diagnosis and routine maintenance where reliable leak localization speeds repairs. Note: follow refrigerant handling rules and local regulations; this kit is an inspection and dye tool, not a refrigerant charging station.
