For more than 40 years, Honeywell has served customers with trusted automotive brands including FRAM®, Bendix®, Autolite®, and Prestone®. You can add to these trusted names the Genetron® brand with 134A and 134a+UV refrigerants.

Genetron®134a meets industry standards for all automotive air conditioning systems that use R-134a or HFC-134a refrigerant. This non-ozone depleting alternative is the environmentally safer choice for refrigerant technology, and is leading the auto industry away from CFC dependency.

To help reduce unnecessary refrigerant leaks and make it easier for consumers and professionals to locate and repair leaking auto air conditioning systems, Honeywell launched our proprietary Genetron 134aUV product in 1999. Genetron 134aUV refrigerant comes with a fluorescent dye pre-mixed and specially formulated to make leak detection simple and easy.
