Icon representing HFC R442A gas cylinder, for use on the web.

R442A (RS-50) R442A, also known as RS-50, is an HFC blend that is suitable for use in low and medium temperature refrigeration applications such as those used in commercial refrigeration. It can be used as a retrofit replacement for R22, R404A or R507 systems, including commercial and transport refrigeration. R442A has a low GWP, approximately half that of R404A or R507A, offering substantial environmental benefit.
