Our Straight Male JIC x Male NPT hydraulic adapters are vital fittings designed to create secure connections in hydraulic systems for transferring fluids and gases. The male end features a JIC (Joint Industry Council) connection, which utilizes a 37-degree flare seating surface and parallel threads, as defined by SAE J514. This design is common in fluid power applications, ensuring a reliable mechanical seal by establishing contact between the male flared seat and the female coned seat. On the other end, the male NPT (National Pipe Taper) connection uses tapered threads to seal pipes through thread deformation, providing a strong metal-to-metal connection when tightened. The nominal pipe size for NPT connections can be identified by measuring the thread diameter and subtracting 1/4". While NPT connections are suitable for single assembly applications, they are not recommended for frequent disassembly due to potential wear on the threads. These adapters are ideal for professionals seeking efficient and dependable hydraulic solutions across various applications.
