FJC DyEstercool A/C Refrigerant Oil

FJC DyEstercool A/C Refrigerant Oil is an ester-based mobile air conditioning oil with fluorescent leak detection dye already blended in. It is made for R-134a and R-12 automotive A/C systems, including systems retrofitted from R-12 to R-134a. Because the dye is in the oil, you don't need a separate dye injection step. This makes it a practical A/C compressor oil and UV leak detection dye in one product.

Key Features:

• Ester refrigerant oil with FJC fluorescent leak detection dye
• 100 viscosity
• Compatible with mineral, ester, paraffin and PAG oils, so one oil can cover many applications
• Helps prevent acid formation and inhibits corrosion while lubricating the system
• Dye shows up under a standard UV inspection light
• Made in the USA

Usage Note: A full system charge during normal service gives the best dye fluorescing. A partial charge can be added to a system that already contains dye.

Technicians and shops can use DyEstercool to simplify A/C service and cut down on the number of oils they stock. It lubricates the system and also makes leaks easy to find later.
