Refrigerant cylinder color codes.

in Thermodynamics Forum

Here I am mentioning some of the most commonly used refrigerants and their cylinder color codes:

R134A - Light Blue

R402A - Light Brown

R407C - Chocolate

R717 - Silver

-----------------------------------------------------------------------------------------------------------------

Some phased-out refrigerants and their color codes:

R12 - White

R22 - Green

R500 - Yellow

R502 - Orchid
