JIC 37 degree flare fittings defined by the SAE J514 and MIL-DTL-18866 standards, which is a type of flare fittings machined with a 37 degree flare seating surface.
37° flare fittings perform well in severe applications where vibration, high pressure, and thermal shock exist. The flare fitting sleeve insures tube alignment with the fitting body axis and minimizes mechanical strain on the tube.
SAE 45 degree fittings are a type of fare fittings machined with a 45 degree flare seating surface. SAE 45° flare connections are commonly used in automotive applications as well as military and oil gas industry. SAE fittings are typically made from steel and stainless steel. SAE and AN/JIC connections are incompatible due to the different flare angle.
QC hydraulics can offer stainless steel 37 degree flare fittings and 45 degree flare fittings.
