Abstract:
A fitting, such as an anti-blowback fitting, that includes a friction reducing device that enables easy removal of the fitting from a high pressure connection such as one associated with an HVAC unit. When used in connection with refrigeration, anti-blow back fittings function to keep the refrigerant in the hose to which it is connected in order to minimize or prevent the refrigerant from escaping to the environment. In certain embodiments, a friction reducing device is positioned in the fitting, and decreases the load on the rear housing, which enables easy rotation of the outer or swivel housing of the fitting to remove the same from the high pressure connection. In certain embodiments, the friction reducing device is a thrust bearing.
