Its function is to connect a flexible refrigerant hose to a rigid threaded component, while simultaneously changing the direction of the flow by 90°. This fitting has been used in numerous industrial, marine, generator, and Cummins automotive applications for many years. Its location is Corrosion Resistor / Coolant Filter Plumbing. Made of steel.
It is found on Cummins N14, NTC, NT-855, NTA-855, ISC 8.3, QSC 8.3, ISL 8.9, ISL9, QSL9, C8.3, 6C8.3, G8.3, and GTA8.3 engines.
The most important feature for identifying it is the 90° + 3/8″ male NPTF × 3/8″ hose barb connection. Correct compatibility is determined primarily by: Engine Model + ESN + CPL + corrosion resistor assembly configuration, not by the vehicle’s model year.
