Type III — Low-PressureQuestion 188 of 240
Low-loss fittings on recovery hoses are important on low-pressure work because they:
a.Speed up the compressor
b.Increase system pressure
c.Cool the refrigerant
d.Cut connection losses
Explanation
Low-loss fittings seal automatically to release as little refrigerant as possible each time hoses are connected or disconnected. This reduces emissions and conserves refrigerant on every job. They are good practice on all recovery work, not only low-pressure.
