Purpose & Audience

Supercool 39241B-YF is a cooling-system stop-leak fluid with UV dye for R-1234yf refrigerant circuits. It targets technicians and fleet maintainers who service trucks and need to seal small leaks without disassembly.

Deciding Specification

The fluid is formulated specifically for R-1234yf systems and contains no polymers, so it will not clog components or recovery equipment. It stops leaks in evaporators, condensers, hoses, gaskets, seals and O-rings while the UV dye pinpoints the repair area.

Build Integration

The 1 oz liquid dose treats a single vehicle system and installs through the standard service port with common injection tools. It frees the technician from component removal and leaves the refrigerant circuit clean for future service.

Questions about this item

What does the 1 oz container size mean for treating a typical A/C system?

The 1 oz bottle treats one vehicle's R-1234yf cooling system by circulating through evaporators, condensers, hoses, gaskets, seals and O-rings to stop small leaks without polymers.

How does the R-1234yf compatibility affect which vehicles I can use this on?

This stop leak is formulated only for systems running R-1234yf refrigerant, so it matches newer trucks and cars that specify that fluid type.

What do I need to connect this product to the service port?

The liquid comes in a 1 oz box container; you will need a standard R-1234yf injection hose or adapter that fits your service port to introduce it.
