Product Details

Universal Air’s PAG 100 (R-134a) Oil + UV Dye line is built for technicians servicing automotive air conditioning systems that require PAG 100 lubricant.

What It Helps Address

• Low refrigerant charge caused by small A/C leaks
• Hard-to-locate seepage at hoses, O-rings, or service connections
• Noise or reduced cooling performance related to improper lubricant service
• Routine A/C maintenance on Toyota Yaris and Scion iA platforms
• Leak tracing after compressor, condenser, or line service

Installation Notes and Tips

Verify the vehicle’s A/C system specification before service and confirm PAG 100 is the correct lubricant for the application. Use standard A/C service procedures, keep the system clean and sealed, and inspect with UV light after operation to locate dye traces. For fitment-based searches, this part is listed for 2019 Toyota Yaris, 2019 Toyota Yaris R, 2017-2018 Toyota Yaris iA, and 2016 Scion iA. RO0909B should be matched to the vehicle’s refrigerant and oil requirements before use.
