Frequently Asked Questions
Q: What refrigerant systems is this A/C Oil & Dye Injector compatible with?
A: This injector is designed specifically for R-134a refrigerant systems, which are found in the majority of passenger vehicles and light trucks manufactured after 1994. It features a standard 1/4 SAE low-side quick coupler for easy connection to the low-side service port.
Q: Can I use this tool to inject both UV dye and compressor oil?
A: Yes! The Car A/C Oil & Dye Injector is versatile enough to handle both UV leak-detection dye and A/C compressor lubricating oil. Simply fill the 30 ml cylinder with your chosen fluid, connect to the low-side port, and inject — it's that straightforward.
Q: Do I need special skills or equipment to use this injector?
A: No special skills are required. The 1/4 SAE quick coupler is a standard, tool-free connection used widely in automotive A/C service. The injector is designed for DIY-friendly use at home, though basic knowledge of your vehicle's A/C system is recommended. Always follow your vehicle manufacturer's service guidelines when working with refrigerant systems.
Q: How much fluid does the injector hold?
A: The injector has a 30 ml capacity, which is ideal for a single-service injection of UV dye or compressor oil — the right amount for most routine A/C maintenance tasks without overfilling.
