Abstract
The invention is a system and associated connection fitting for connecting a refrigerated line or air conditioning hose to the compressor unit or component on one end and the evaporator unit or component on the other end of a residential or commercial air conditioning or refrigeration system. The hose will be of a construction, which as well as having a relatively high bursting strength, will also not allow the refrigerant to permeate through the hose and escape into the outside environment. The associated connecting fitting allows the hose to be connected to the compressor/evaporator unit. The mounting surface of the fitting will allow it to either slide over or fit into the corresponding fitting on the compressor and/or evaporator unit. The opposite end, which shall connect to the hose assembly, will have flanges and “O” rings which when clamped will provide a secure connection as well as prevent loss of refrigeration.
