MIDDLE EAST - Reputable refrigerant manufacturers and distributors continually caution contractors to check and be sure of the purity and legality of the refrigerants they purchase. They suggest two ways to do so: Stay with brand names accessed through respected channels and be aware that if a price seems too low, the refrigerant could be suspect.
These reminders are drawing special attention with the announcement in May by DuPont's United Kingdom operation that there is "a concern over the prevalence of counterfeit R-134a refrigerant within the Middle East."
