JIC fittings, defined by the SAE J514 and MIL-DTL-18866 standards, are a type of flare fitting machined with a 37-degree flare seating surface. JIC (Joint Industry Council) fittings are widely used in fuel delivery and fluid power applications, especially where high pressure (up to 10,000 pounds per square inch (690 bar)) is involved.
An icon of the era and of American general aviation, the J-3 Cub has long been loved by pilots and nonpilots alike, with thousands still in use. Piper sold 19,073 J-3s between 1938 and 1947, the majority of them L-4s and other military variants. After the war, thousands of Grasshoppers were civilian-registered under the designation J-3.
