Comments regarding tubes and hoses:
^
Some R-134a tubes and hoses have reversed male/female connections to prevent interchangeability with R-12 components.
R134A Service Tools & Equipment
^
R-12 and R-134a require separate and non-interchangeable sets of recovery, recycle, and recharge equipment, because the refrigerants and lubricants
are not compatible and cannot be mixed even in the smallest amounts.
^
DO NOT attempt to use one set of equipment for both R-12 and R-134a, as all equipment contains residual amounts of refrigerant and/or lubricant,
