KAISAL AC Oil Injector 2oz Aluminum Refrigerant Oil/Dye Kit — R134a/R410A/R22 Compatible, Brass Quick Coupler

This injector combines a 60 ml (2 oz) aluminum reservoir, a high-pressure hose with 1/4" SAE thread, and a durable R134a quick coupler so you can service automotive and household air conditioning systems faster and cleaner. Built to accept POE or mineral oils and leak-detection dyes, the KAISAL injector simplifies oil/top-up jobs without requiring bulky equipment or complex adapters.

How do I use the injector safely during a recharge?

Operation is straightforward: fill the cylinder, attach the low-pressure quick connector to the service port, ensure the shut-off valve is closed before adding additives, then pressurize and release oil into the system. Follow vehicle or appliance manufacturer service procedures and work with the system at appropriate pressures.

• Fill reservoir with up to 2 oz (60 ml) of compressor oil or fluorescent dye.
• Connect R134a low-pressure quick coupler to the low-side service port.
• Open the valve to introduce oil once pressure is set; close when finished.
• Observe standard safety precautions and wear protective equipment.

Which refrigerants and oils is this injector compatible with?

KAISAL designed the injector for broad compatibility across common refrigerants and oil types used in HVAC and automotive systems. It accepts R134a, R410A, R22, R12, R1234yf and other gases, and works with both POE and mineral compressor oils as well as fluorescent leak-detection dyes.

• Refrigerants: R134a, R410A, R22, R12, R1234yf, and others.
• Oils: POE and mineral oils supported without seal damage.
• Dyes: Compatible with standard fluorescent leak-detection dyes.

What features make this tool durable and leak-resistant?

The body is machined from aluminum alloy for corrosion resistance and light weight while the R134a coupler and fittings use solid brass for long-term sealing and wear resistance. The hose assembly is rated to high pressures and the 1/4" SAE threaded port includes a knurled grip for quick, secure connections.

• Aluminum alloy cylinder reduces corrosion and residue.
• Brass R134a quick connector resists wear and rust.
• High-pressure hose rated up to 600–3000 PSI for safe operation.
• 1/4" SAE threaded port with non-slip knurled grip for easy handling.

How much fluid does it hold and how precise is the filling?

The injector holds 2 ounces (60 ml), a practical size for topping up compressors without overfilling. Its design promotes thorough transfer with minimal leftover residue, enabling controlled, repeatable additions during service calls.

• 2 oz (60 ml) capacity suited for common top-up volumes.
• Internal design minimizes waste and ensures efficient transfer.
• Quick-connect and knurled fittings speed up repeated tasks.

Who this is for: the KAISAL AC Oil Injector is aimed at HVAC technicians, mobile mechanics, and experienced DIYers who need a portable, reliable way to add compressor oil or leak-detection dye to automotive and residential air conditioning systems. It’s especially useful for quick service calls, diagnostic leak checks, and situations where a compact, well-sealed injector is preferable to larger bulk equipment. Note: use only as directed and adhere to system manufacturer recommendations and safety practices.

Warranty & support: KAISAL backs the injector with a two-year warranty and technical assistance within 24 hours for troubleshooting and service questions.
