A #4 JIC fitting refers to a specific size in the Joint Industry Council (JIC) fitting standard, which is commonly used for hydraulic systems. The #4 size corresponds to a 7/16-20 UNF (Unified National Fine) thread, and it is designed to fit a tube with an outer diameter of 1/4 inch. JIC fittings are known for their 37-degree flare seating surface, providing a reliable, leak-proof connection.
