Forane® 427A is a 100% HFC blend made of R-32, R-125, R-143a and R-134a. It does not contain any flammable hydrocarbons. It is consequently compatible with the elastomers and plastic materials usually compatible with R-407C and R-404A. Before any retrofit, the condition of any elastomers seals, gaskets and valve packing should be carefully checked. If these parts are damaged they must be replaced to prevent leakage.
