Refrigerant Regulation

USA EPA rule on HFC refrigerants — important information

Any specified components intended for use with an HFC refrigerant or refrigerant blend containing an HFC is for servicing existing equipment only, unless the end use is not covered by the Environmental Protection Agency (EPA) Transition Rule. Before using the specified component with a regulated substance, please check the Environmental Protection Agency (EPA) rules at the EPA website.

More information about the suitable refrigerants for each product, please access our Product-Selector Software.

To understand what refrigerant the specified component is intended for use with, please see the tables below:
