Tellegloww Oil and Dye Injector Kit 1oz/30ml Hand-Push Injector with UV Flashlight & Multi-Adapters

This all-in-one toolkit combines a sturdy aluminum alloy oil injector, three low-side quick couplers, an R410A mini split adapter, valve-core remover, a 100-LED UV flashlight and protective UV glasses so you can locate and treat refrigerant system leaks without relying on a running compressor. Parts are made from aluminum and brass for corrosion resistance, and the kit supports common refrigerants including R134a, R1234yf, R22 and R410A.

How does the injector actually deliver oil or dye to the system?

The hand-push compressor (1oz/30ml capacity) forces oil or fluorescent dye into the low-side port using a direct mechanical push—no external compressor required. A simple twist-and-press operation controls the volume delivered so you add only the amount needed.

• 1oz (30ml) aluminium hand-push injector for precise dosing
• Push-in operation: twist handle to control flow
• No running compressor needed—reduces risk to a weak compressor
• Brass 1/4" SAE-compatible fittings for secure connection

Which vehicles and refrigerants are compatible with this kit?

The kit was designed to work with a broad range of automotive and small HVAC systems that use R134a, R1234yf, R22, R410A and similar refrigerants. It includes multiple low-side couplers and a mini split adapter to match common service ports safely and securely.

• 13mm R134a low-side quick coupler included
• 14mm R1234yf low-side quick coupler included
• R410A mini-split adapter for HVAC systems
• Compatible with many R22, R404a and SAE applications

What leak-detection tools are included and how do they help?

The kit pairs a 100-LED UV flashlight with fluorescent dye capability and yellow UV-protection glasses so you can spot dye under UV light while protecting your eyes. The flashlight’s concentrated purple LEDs illuminate dye traces, and the glasses reduce glare for clearer detection.

• 100-LED UV flashlight (requires 6x AA batteries, not included)
• Yellow UV protective glasses to shield eyes and improve visibility
• Bright UV light turns invisible dye marks into easy-to-read highlights
• Valve-core remover and adapters allow safe access to low-side ports

How durable and safe are the components during repeated use?

Key wear parts are aluminum alloy and brass to resist corrosion and maintain reliable connections under service conditions. The quick couplers and valve tools are built for repeated engagement, while protective glasses reduce UV exposure during inspections.

• Aluminum alloy main body for lightweight strength
• Brass fittings for leak-resistant connections
• UV glasses with abrasion-resistant lenses for safety
• Compact kit design for workshop portability and storage

Who is this for: The Tellegloww Oil and Dye Injector Kit is intended for automotive technicians, HVAC service pros, and knowledgeable DIYers who need a compact, manual way to add oil or fluorescent dye and confirm leaks with UV light. It’s ideal when you want controlled dosing, multiple low-side adapters and a portable UV inspection setup without relying on a compressor. Note: follow refrigerant-handling regulations and use appropriate PPE; UV flashlight requires six AA batteries (not included).
