The Tellegloww AC Leak Detector Kit is designed to help locate difficult-to-see refrigerant leaks in compatible automotive and HVAC air-conditioning systems. It includes a UV dye injector, low-side quick coupler, mini-split adapter, replacement O-rings, UV glasses, and flashlight, providing a practical set of tools for visual leak detection.

Key Specifications

  • Brand: Tellegloww

  • Product Type: AC Refrigerant Leak Detection Kit

  • Compatible Refrigerants: R1234yf, R134a, R410a

  • Detection Method: UV fluorescent dye

  • Connection: Low-side quick coupler

  • Included Accessories: UV glasses, flashlight, O-rings, adapters, dye injector

Main Features

UV Dye Leak Detection

The kit uses fluorescent UV dye to make refrigerant leaks easier to identify. Once the dye has circulated through a compatible AC system, a UV light can help reveal traces around leaking connections and components.

Multi-Refrigerant Compatibility

Designed for use with R1234yf, R134a, and R410a systems, the kit can be useful for both automotive air-conditioning applications and compatible HVAC equipment. Always verify the refrigerant and fitting requirements before use.

Low-Side Quick Coupler

The low-side quick coupler is designed to simplify connection to compatible AC service ports. A secure connection helps make dye injection more convenient during diagnostic work.

Mini-Split Adapter

The included mini-split adapter expands the kit's usefulness for compatible mini-split and HVAC systems. This can make it a practical addition to a technician's diagnostic toolbox.

UV Glasses & Flashlight

The included UV glasses and flashlight help improve visibility when searching for fluorescent dye. Together, they provide the basic equipment needed to inspect suspected leak locations under UV illumination.

Replacement O-Rings

Sealing O-rings are included to help maintain proper connections and replace worn or damaged seals during servicing. This is particularly useful when working with multiple fittings or repeatedly using the kit.

Performance

Performs exceptionally well for:

  • Locating suspected AC refrigerant leaks

  • Inspecting automotive AC systems

  • Checking compatible R410a HVAC systems

  • Diagnosing mini-split systems

  • Finding leaks around fittings, hoses, and connections

Pros

  • Supports R1234yf, R134a, and R410a applications

  • Uses highly visible UV dye for leak identification

  • Includes low-side quick coupler

  • Comes with mini-split adapter

  • UV glasses and flashlight included

  • Replacement O-rings add convenience

  • Compact kit for workshop or mobile diagnostic use

Cons

  • Refrigerant and fitting compatibility must be confirmed before use

  • UV dye only helps identify leaks after it has circulated through the system

  • Professional service equipment may still be required for complete AC diagnosis and repair

  • Incorrect handling of refrigerants can be hazardous

Who Should Buy This?

Ideal for:

  • Automotive AC technicians and DIY mechanics

  • HVAC technicians working with compatible systems

  • Users troubleshooting suspected refrigerant leaks

  • Workshops needing a compact UV-based leak detection kit

Final Verdict

The Tellegloww AC Leak Detector Kit provides a convenient collection of tools for identifying suspected refrigerant leaks using UV dye. Its multi-refrigerant compatibility, low-side quick coupler, mini-split adapter, UV glasses, flashlight, and replacement O-rings make it a versatile diagnostic kit for compatible automotive and HVAC applications. For DIY users and technicians who need a straightforward visual method for locating difficult-to-find AC leaks, it can be a useful addition to the diagnostic toolbox.
