Our Series 2405 Straight Male JIC x Female NPT Rigid one-piece hydraulic adapters are essential components in hydraulic systems, providing a reliable connection between hoses and pipes. Made from durable carbon steel, these adapters feature a male JIC end that connects to a female NPT fitting. JIC (Joint Industry Council) fittings, defined by SAE J514, are compression fittings with a 37-degree flare seating surface and parallel threads, commonly used in fluid power systems. The connection is made by ensuring contact between the male flared and female coned seat, creating a robust mechanical seal. NPT (National Pipe Taper) connections, on the other hand, use tapered threads to seal pipes for fluid and gas transfer, making them ideal for single assembly applications. To identify the nominal pipe size, you can measure the thread diameter and subtract 1/4". While NPT connections provide a metal-to-metal seal, they are not recommended for frequent assembly and disassembly due to potential thread wear. The Series 2405 adapters enhance system performance and are a crucial choice for professionals seeking dependable hydraulic solutions.
