Universal/Ester Leak Detection Products
Tracerline® Universal/Ester dyes are compatible with R-1234yf, R-134a, and other widely used refrigerants. Tracerline dyes can remain safely within the system. That means once the repair is made, the dye can be used as part of a preventative maintenance program. Click on the links below for Universal/Ester compatible products for automotive leaks.
