The Series 2404-L-SS Straight Male JIC x Male NPT hydraulic adapters, made from high-quality stainless steel, are designed with an extended overall length compared to the standard 2404 Series, providing enhanced versatility in hydraulic system applications. Featuring a male JIC (Joint Industry Council) end, these adapters utilize a 37-degree flare seating surface and parallel threads, as defined by SAE J514, which are commonly used in fluid power systems for their reliability. The seal is established by contact between the male flared seat and the female coned seat, creating a robust mechanical connection. The male NPT (National Pipe Taper) connection on the other end employs tapered threads to effectively seal pipes for fluid and gas transfer through thread deformation, ensuring a strong metal-to-metal connection. The nominal pipe size can be determined by measuring the thread diameter and subtracting 1/4". While NPT connections are ideal for single assembly applications, they are not recommended for frequent disassembly due to potential wear on the threads. These stainless steel adapters offer professionals dependable and efficient hydraulic solutions, ensuring optimal performance in a variety of applications.
