NPT (National Pipe Thread) and JIC (Joint Industry Council) 4 are both types of fittings used in fluid systems, but they differ in design and application. NPT fittings have a tapered thread that seals by wedging the threads together, whereas JIC 4 fittings use a 37-degree flare seating surface to create a metal-to-metal seal, providing a more reliable and reusable connection.
