Supercool 22816 UV Leak Detection Dye Green 8 oz

SKU CH-NQQS-DT8VA

Fluorescent green dye pinpoints leaks in R134a and HFO-1234yf air-conditioning systems, safe for hybrid and electric vehicles, and meets SAE J2297 certification

  • Product colorGreen
  • Detect leaks fast with bright green UV fluorescence
  • SAE J2297 certified for R134a and HFO-1234yf systems
  • Safe for hybrid and electric A/C systems
  • 1/4 oz per vehicle treats a full system
  • 97 specific gravity ensures proper refrigerant mixing

Automotive A/C Leak Detection Dye

This Supercool 22816 UV dye is formulated for automotive air-conditioning systems. The fluorescent green liquid pinpoints refrigerant leaks under UV light. It is suitable for professional technicians and DIY owners servicing R134a or HFO-1234yf circuits. The 8 oz bottle treats multiple vehicles at the standard dilution ratio.

Sustained System Compatibility

The dye carries SAE J2297 certification for leak detection in both R134a and HFO-1234yf systems. Its 0.97 specific gravity and 300 SUS viscosity at 100 °F ensure stable circulation through the refrigerant loop during extended operation. The 100 viscosity index indicates consistent flow across temperature swings. It is also rated safe for hybrid and electric A/C compressors.

Replaces Generic Non-Certified Dyes

This product upgrades from uncertified fluorescent additives that lack SAE J2297 validation. The jump is worth it when a shop or owner needs documented compliance for R134a and HFO-1234yf systems, including hybrid and electric platforms. It is not for buyers who need a sealant or a refrigerant charge.

Questions about this item

Does the 0.97 specific gravity or 300 SUS viscosity generate extra heat or power draw when the A/C runs continuously?

The dye itself adds no heat or electrical load; it simply circulates with the refrigerant and oil at 0.97 specific gravity and 300 SUS viscosity.

What A/C system components or tools do I need on the vehicle for this 8 oz bottle to work?

You need a functioning R134a or HFO-1234yf system with a service port, plus a UV inspection lamp to see the fluorescent dye.

Will this SAE J2297 dye harm seals or sensors in an older R134a system I plan to keep?

It is certified safe for hybrid and electric A/C systems and meets SAE J2297, so it is compatible with existing R134a hardware.
