i do agree i love not having frozen oily hands but didn't think that was the reason the epa requires the fittings to be used. I also love the fact that you can cross contaminate system from having beat refrigeratnt in your hoses and you may for get before hooking them up to another system. I know the amount is very minor but its the thought that counts.
Low-Loss Fitting - any device that is intended to establish a connection between hoses, appliances, or recovery/recycling machines, and that is designed to close automatically or to be closed manually when disconnected to minimize the release of refrigerant from hoses, appliances, and recovery or recycling machines.
I emailed the EPA and we'll see what the people in charge of these laws have to say. Its say they will get back with-in 24hrs but we will see about that. I
am interested to see if they even have a specific answer!
