LeakFinder Fluorescent Leak Detection Dyes are the perfect solution for anyone working on a vehicle’s total system. These concentrated dyes fluoresce brighter than similar products in the same price category.
Universal A/C Dye provides precise leak detection for all systems containing R-134a, R-1234yf, or other widely used refrigerants.
These specialty dyes can be safely added and will not affect the lubricant properties of A/C systems or change how the equipment works.

5 oz (148 ml) foil pouch universal/ester A/C oil with fluorescent dye. Universal formula designed for both PAG and mineral oil A/C systems.

CAUTION: Not for use in hybrid vehicles with electrically driven A/C compressors.

Features:

• Moisture-resistant pouch
• Protects against contamination
• Simple pour, easy to use
• For replenishing A/C compressor oil
• For installation and remanufacturing
• Perfect for preventative maintenance

LeakFinder LF200CS AC Leak Sealant seals pinhole leaks in accumulator/receivers, evaporators, condensers, O-rings, hoses and more. The patented DUAL-ADAPTER can connect to either R-134a or R-1234yf systems.

Fix hard-to-find leaks and extend the service life of the AC system. The powerful sealant formula is also compatible with electrically-driven AC compressors used in hybrid/electric vehicles.

Prevent new leaks from developing and provide ongoing sealing protection with the LF200CS AC Leak Sealant
