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.

Yes, the difference between pipe fittings and JIC (Joint Industry Council) fittings primarily lies in their design and application. Pipe fittings typically rely on threads to create a seal, often used in plumbing and fluid transfer systems. In contrast, JIC fittings utilize a 37-degree flare seating surface to create a metal-to-metal seal, commonly used in high-pressure hydraulic applications for their leak-resistant and vibration-resistant properties.
