Tellegloww Refrigerant Leak Detector Kit R1234yf/R134a 30ml Hand-Push Dye Injector with UV Flashlight & Probe

Tellegloww Leak Detector Kit is a complete HVAC and automotive refrigerant leak inspection set with a 30ml hand-push dye injector, UV flashlight, protective eyewear and multiple quick couplers for R1234yf, R134a and R410a systems.

This compact kit combines a lightweight aluminum alloy hand-push compressor for injecting up to 1 oz (30 ml) of UV-visible dye, a 51-LED UV inspection flashlight, a flexible probe leak detector, and adapters for common refrigerants so you can find and confirm leaks faster. It’s designed to work on automotive and split-system air conditioners, offering visual dye tracing plus an electronic sniffing probe for quicker identification in tight spaces. All items are built from metal and durable plastics to withstand workshop use.

How do I inject dye and check a system?

Attach the included low-side quick coupler for your refrigerant type (R134a or R1234yf) or the R410A mini-split adapter, connect the hand-push compressor, and gently press to introduce dye into the system. Let the system run so the dye circulates; then scan suspicious areas with the UV flashlight and wear the protective glasses supplied.

• Hand-push injector holds 30 ml (1 oz) of UV dye for controlled dosing
• Aluminum alloy body and brass 1/4" connectors for durability
• Includes R134a and R1234yf low-side couplers plus R410A adapter
• Core remover allows safe access to service ports

What leak types and refrigerants can this kit help detect?

The kit is compatible with common refrigerants (including R22, R134a, R404A, R410A and R1234yf) and works with most UV-reactive oil dyes used for leak tracing. The detector’s probe and UV light help spot dye deposits and small oil stains around fittings, hoses, evaporators and condensers.

• Electronic leak detector probe for airborne refrigerant detection
• UV dye + 51-LED UV flashlight reveal visual staining and fluorescence
• Protective glasses reduce eye exposure to UV while enhancing dye visibility
• Flexible probe (approx. 8.46 in) reaches confined spaces

How does the electronic leak detector alert me?

After power-up the detector takes a few seconds to initialize, then provides audible beeps and visual flash indicators when it senses refrigerant vapors. The tone and flash rate increase as the concentration rises, helping you home in on the leak source more quickly.

• Audible and flashing indicators for intuitive feedback
• Probe tip designed for pinpointing small leaks in tight spots
• Textured handle improves grip during inspections
• Detector runs on batteries (check manual for battery types and installation)

How do I protect myself and my equipment while using dye?

Always avoid direct contact with skin and eyes when handling UV dye; wear the included protective glasses during inspection and follow safe handling instructions. Use only the recommended dye types for air conditioning systems and ensure proper system service procedures when introducing foreign substances.

• Protective glasses extend coverage on both sides to block stray UV
• Keep dye away from skin and rinse immediately if contact occurs
• Use core remover to avoid damaging service ports during connections
• Follow manufacturer instructions for dye compatibility and quantities

Who this is for: technicians, HVAC service professionals and DIY automotive enthusiasts who need a portable, multi-refrigerant leak inspection solution. If you service automotive A/C or mini-split systems and want combined visual dye tracing with electronic sensing and adapters to fit R134a, R1234yf and R410A ports, this kit provides the basic tools to find and verify leaks quickly. It’s best suited for routine diagnostics and locating visible leaks; always consult system service manuals and follow safety guidelines when adding products to refrigerant circuits.
