TSI Supercool A/C UV Leak Dye — Yellow SAE-Certified, 8 oz Self-Measure Bottle (Treats 32 Vehicles)

Whether troubleshooting automotive air conditioning or servicing hybrid and electric vehicles, a reliable trace dye speeds diagnosis and helps avoid unnecessary component replacement. This yellow dye is SAE certified for R134a and HFO-1234yf systems, designed to work with PAG, PAO, ester and mineral oils, and packaged in an 8-ounce self-measure bottle that treats up to 32 vehicles.

How will this dye help me find A/C leaks faster?

When added to the A/C system, the dye circulates with the refrigerant and oil. Any leak exposed to ultraviolet light will glow, revealing seepage points that are otherwise hard to spot. This reduces inspection time and pinpoints the exact source of loss for targeted repairs.

• Highly visible yellow formulation under UV lamps
• Circulates with refrigerant and oil to trace leaks throughout the system
• Detects small, slow leaks as well as larger failures
• Packaged in a self-measuring bottle for accurate dosing

Is this dye safe for my vehicle’s A/C components and equipment?

This product is formulated without solvents and is compatible with common A/C oils and recovery gear, minimizing risk to system materials and service equipment. Anti-wear agents and friction modifiers are included to support compressor operation while antioxidants help prevent sludge and deposit formation.

• No solvents — safe for seals, hoses and recovery machines
• Compatible with PAG, PAO, ester and mineral oils
• Includes anti-wear agents and friction modifiers to reduce wear
• Antioxidants reduce chances of sludge and deposit buildup

Which refrigerants and vehicle types is this dye certified for?

TSI Supercool 22816 is SAE certified for use with both R134a and HFO-1234yf systems, making it suitable for the majority of modern passenger vehicles. It’s also labeled safe for hybrid and electric vehicle A/C systems, allowing technicians to use one product across varied drivetrains.
