I have not seen fake CAT's that are Gen V or Gen VI. Gen V and VI have the RedTip and Fatter Windless. All the fakes I have seen have been pervious generations. Go to North American Rescue or Rescue Essentials to get your CAT's.

Mick boiled it down to very simple things, if it's high pressure or high volume you get a TQ. Better to error on the side of caution here and throw on a TQ.
