Qnbes AC Oil Dye Injector for R134A/R12/R22 — 2 oz Solid Brass with Quick-Couplers

This compact injector kit gives technicians and DIYers a reliable way to introduce lubricants or UV dye into automotive and small HVAC systems without disassembly. Built from solid brass and fitted with quick couplers for the low-pressure service port, the tool balances durability with user-friendly connections. It accommodates POE and mineral oils and works with common refrigerants used in vehicle and home air conditioning systems.

How does the Qnbes injector connect to my vehicle's low-side service port?

Connection is straightforward: the kit includes a low-pressure R134A snap coupler and a 1/4" SAE adapter designed to mate with standard low-side fittings. Once attached, the injector forms a sealed path for controlled filling or dye injection while the system runs.

• Includes R-134a snap coupler for low-side port connection
• 1/4" SAE female to low-pressure quick coupler adapter included
• Solid brass fittings provide reliable sealing and resist wear
• Designed for use while compressor is running to distribute product

What capacity and materials should I expect from this oil and dye injector?

The injector holds 2 oz (60 ml), a practical volume for topping systems or performing a single leak-detection job without repeated refills. Construction is solid brass for corrosion resistance, long life, and tight sealing to minimize leaks during use.

• 60 ml (2 oz) refillable syringe-style reservoir
• Solid brass body resists corrosion and mechanical wear
• Good sealing design to prevent accidental leakage
• Quick disconnect capability for rapid workflow

How do I use the injector safely and effectively?

Operating the injector requires the air conditioning compressor to be running so the additive circulates. Follow the included steps to load the desired amount, connect to the low-side service port, open the valve to inject, and then clean the tool after use.

• Start the vehicle and run AC at maximum airflow with compressor engaged
• Close injector valve, fill reservoir with oil or dye, tighten cap securely
• Attach snap coupler to low-side service port and open injector valve to add product
• After use, clean tool with brake cleaner to remove residue

Which refrigerants and oils is the injector compatible with?

The Qnbes injector is designed for use with R134A, R12, and R22 systems and accepts a wide range of oils, including POE and mineral types. It is suitable for automotive air conditioning systems and smaller home or office units where low-side service access is appropriate.

• Compatible with R134A, R12, R22 refrigerant systems
• Accepts POE and mineral oil formulations and fluorescent dye
• Useful for leak detection and oil top-ups in vehicles and small HVAC units
• Universal quick-connect fittings for common service ports

Who is this for: The Qnbes AC Oil Dye Injector is aimed at mechanics, HVAC technicians, and competent DIYers who need a compact, durable tool for injecting oil or UV dye into low-side service ports. It suits anyone performing routine maintenance, troubleshooting leaks, or topping lubrication in automotive and small refrigeration systems and who prefers a brass-built, reusable injector with quick-connect convenience.
