Review: Find leaks or add oil in your car or just about any other system with this kit. - This is a very complete kit. You use the aluminum cylinder to force oil/dye into your system, then use the flashlight to check for leaks. Has fittings for 1234YF (newer automotive refrigerant) as well as R134A, and even the older style fittings that you might find on an R12 system or home unit. Lots of o-rings in common sizes to fix leaks if you do find some as well as a great selection of valve cores. The sniffer seems to work, but I don't usually rely on them, so check other reviews. Both the flashlight and sniffer will need batteries before you use them. ## Features - Packing List: products include 1 AC oil injector, 1 R134a low side quick coupler, 1 R1234yf low side quick coupler, 1 R410 mini split adapter, 1 valve core remover, 1 oil UV Dye leak detector (4 AAA batteries not included), one 28LED UV flashlight ( 3 AAA batteries not included), a pair of UV protective glasses, 1 box 18 size of 270pcs sealing-oring, 1 box of 39 pcs valve core assorted with 1 pcs valve core remove and install tool; Our uv leak detection kit helps check for car AC leaks - Undefined: our refrigerant leak detector adopts advanced leak detection technology and is able to detect R134A, R1234yf, R410A and most refrigerants, compatible with HFC, and mixtures; The main body of the AC oil dye injector is made of aluminum alloy, 1/ 4" connectors compatible with SAE and quick connectors are made of brass, heavy duty materials ensuring durable, products - Easy to Operate: to inject dye or oil, just connect the syringe to the low side of the air conditioning system and screw the handle until the desired amount is reached; The leak detector is ready to use 6 seconds after turning on, you choose suitable sensitivity and then extend the probe to the place to be detected; If there is refrigerant flowing out, it will make a sound and the indicator will flash quickly; The more leakage, the faster the sound will be; See the instructions for more details - Clever Design: the handle of the AC leak detector kit adopts a textured design to increase friction, allowing you to turn it easily even when there is oil on your hands; The practical leak detector is designed with a flexibly adjustable probe, long approximately 8.46 inch, helping you detect small areas; UV protective glasses can not only cover the front of the eyes, but the extended design on both sides prevents UV rays from passing through the places where ordinary glasses miss the protection - Practical Combination: air conditioner leak detector tool comes with R134a, R1234yf low side port coupler snap and R410a mini split adapter, making the kit can be applied with R134a and R1234yf manifold to work on automotive AC systems; The leakage tester is equipped with not only one small UV detection lamp, and an additional UV flashlight and a pair of anti UV glasses, the UV lamp helps detect leaks visually, and the glasses protect your eyes, a practical combination ## Images ![Tellegloww 2-in-1 AC Leak Detector Kit for R1234yf R134a R410a, Electronic Refrigerant Sniffer & UV Dye Injector Tool Set with UV Flashlight, 270pcs O-Rings, 39pcs Valve Cores for Auto & Home HVAC - Image 1](https://m.media-amazon.com/images/I/81mMlZVLC2L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Accurate and Easy-to-Use AC Leak Detector Kit *by A***R on March 14, 2026* This AC Leak Detector Kit is fantastic for anyone working on R1234yf, R134a, or R410a systems.
