TSI Supercool A/C UV Leak Dye Green 8 oz — Self-Measure Bottle, Treats 32 Vehicles, R134a/R12 Safe

TSI Supercool D8 A/C U/V Dye Green is a ready-to-use, self-measure 8 oz dye that helps pinpoint refrigerant leaks in automotive A/C systems and treats up to 32 vehicles.

This fluorescent green dye is made to work with both R134a and legacy R12 systems and is formulated to be safe for hybrid and electric vehicles. It mixes with common compressor oils (PAG, ester and mineral), contains no solvents, and is engineered to be visible under ultraviolet light so technicians and DIYers can locate leaks quickly without risking damage to components or recovery equipment.

How does this dye locate A/C leaks?

The dye circulates through the refrigerant and oil, depositing fluorescent tracer at leak points. When you illuminate the system with a U/V lamp, the dye glows bright green at the source of leakage, allowing fast visual diagnosis.

• Fluorescent tracer visible under UV light for rapid leak identification.
• Circulates with refrigerant and compressor oil to mark internal and external leaks.
• Suitable for both R134a and R12 systems used in many vehicle makes.

Will this product harm my A/C system or recovery equipment?

TSI Supercool D8 is formulated without solvents and designed for compatibility with common A/C oils, minimizing risk to seals, hoses and recovery machines. Proper use follows recommended dosing to avoid over-concentration while preserving system integrity.

• No solvents that could degrade A/C system materials.
• Compatible with PAG, ester and mineral oils used in automotive systems.
• Self-measure bottle dispenses precise 1/4 oz doses to avoid overdosing.

How much vehicle coverage does one bottle provide and how do I dose it?

The 8 oz self-measure bottle contains multiple 1/4 oz doses—each dose is formulated to treat a single vehicle. With standard dosing, one bottle can service up to 32 vehicles, making it economical for shops and mobile technicians.

• 8 oz total volume with 1/4 oz pre-measured dosing per vehicle.
• Treats up to 32 vehicles when used at the recommended dosage.
• Self-measure design reduces waste and speeds application.

Can I use this dye in hybrid or electric cars?

Yes—this dye is safe for hybrid and electric vehicle A/C systems when used as directed. Its solvent-free composition and compatibility with typical compressor oils make it a practical choice for modern vehicle platforms.

• Formulated for use in hybrid and electric vehicle A/C systems.
• Solvent-free to reduce risk to sensitive components.
• Detectable under U/V light for fast, non-invasive inspection.

Who is this for: TSI Supercool D8 A/C U/V Dye Green is ideal for automotive technicians, fleet maintenance teams, and knowledgeable DIYers who need a reliable, solvent-free dye to find refrigerant leaks quickly and economically. It’s especially useful for shops that service a mix of R134a and R12 systems, and for anyone who values precise dosing and minimal impact on system components.
