Tellegloww Leak Detector Kit — 8-Pc HVAC/R Injector & UV Flashlight for R134a R1234yf R410A, 1oz Aluminum Syringe

The Tellegloww 8-piece Leak Detector Kit is a portable HVAC/R UV dye injector and electronic leak detector bundle designed to find refrigerant and oil leaks in automotive and mini-split systems quickly and accurately.

This comprehensive kit combines a 1 oz (30 ml) aluminum hand push oil/dye injector, three low-side/mini-split adapters, a flexible probe leak detector, and a 51-LED UV flashlight with protective glasses so you can both inject tracing dye and visually confirm leaks under UV light. Built from brass and aluminum components with a textured handle, the tools are made for field use on R134a, R1234yf and R410A systems. The package is aimed at technicians and DIYers who need a compact, multi-function set to locate small leaks in AC and refrigeration equipment.

How does the injector deliver dye or oil into an AC system?

The aluminum hand push compressor injects measured amounts of dye or oil into a system through a standard 1/4" connection. You attach the syringe to the low-side service port, then screw the handle to push the selected volume into the refrigerant line without the need for electrical power.

• 1 oz (30 ml) aluminum syringe for precise dosing
• Textured handle for improved grip when oily or wet
• Brass quick connectors for durable, leak-resistant attachment
• Manual operation — no batteries or charging needed for injection

What types of refrigerant and systems will this kit work with?

The kit is compatible with common refrigerants and includes adapters to service automotive and mini-split systems. It supports R134a, R1234yf and R410A applications via the supplied low-side couplers and R410 mini-split adapter.

• R134a low-side quick coupler included
• R1234yf low-side quick coupler included
• R410A mini-split adapter for home HVAC systems
• Core remover for safe service port access

How does the electronic leak detector and UV lamp help find leaks?

The electronic detector senses refrigerant vapors and produces audible and visual alerts whose rate increases with leak size, while the UV flashlight highlights injected dye under darkened conditions. Use the detector probe to scan suspected areas and then inspect joints and stains with the UV light while wearing the supplied protective glasses.

• Flexible ~8.46-inch probe reaches tight spaces
• Detector powers up in seconds; sensitivity adjustable
• 51-LED UV flashlight for clear dye fluorescence viewing
• Protective glasses block UV glare and improve dye contrast

What practical features make this kit durable and easy to use?

Materials and ergonomic design focus on reliability in workshop and roadside conditions. Key parts use brass and aluminum for corrosion resistance, and the textured handle and compact layout keep operations controlled and portable.

• Aluminum alloy injector body resists impact and wear
• Brass fittings and quick connectors for long service life
• Compact case-like assortment for straightforward transport
• Additional UV flashlight included for bright inspection sites

Who is this for: The Tellegloww Leak Detector Kit is intended for HVAC technicians, automotive service professionals, and competent DIYers who work on vehicle air conditioning or residential mini-split systems and need a combined dye injector and electronic leak finder. It suits users who value manual dosing control, durable metal fittings, and the ability to verify dye visually with a UV lamp. Note: batteries are not included, and the kit contains small parts — keep away from children.
