A/C Barrier Hose Identification

[big911fan]

Is there a way to identify if a prior owner replaced any of the A/C hoses with newer barrier hoses?

Do barrier hoses have any type of coding or perhaps a different OD that I can use to positively tell if they've been updated?

Some of the hoses look newer but that's very subjective. I'm looking for a more definitive way to id the hoses.

My barrier hoses have printed on the SAE J2084 or something like that.

AC Hose Question

Thanks guys. I'll check the markings on my hoses. I know the suspect hose (from the compressor to the evaporator) is an old one and needs to be changed.

Hopefully they don't all need to be changed.
