    Different diditals for different refrigerants

    With all the manufacturers telling us to use different gauges for different refers especially the poe oils verses the mineral and ab oils,Do you guys have seperate digitals for r22 and 410a? With there expense being so high,I was wandering? Maybe you just change hoses? Any advice would be appreciated.

    unless you're charging oil into the system -- don't worry about it.
    this oil contamination this is way overblown. POE can handle about 5% mineral without major issues. So how much oil do you think is in those hoses you just removed from your CFC or HCFC system and how much oil charge is in your HFC system?

    Also be sure to purge from your hoses any remaining refrigerant from the previous system.
    keep your ice cold and flame hot
