Our Series 2705 Straight Male JIC x Female NPT Rigid Bulkhead hydraulic adapters are vital components designed for efficient fluid transfer in hydraulic systems. Made from high-quality stainless steel, these adapters feature a male JIC end that connects securely 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 for their reliability. The seal is formed by ensuring contact between the male flared seat and the female coned seat, creating a robust mechanical connection. On the other hand, NPT (National Pipe Taper) connections use tapered threads to effectively seal pipes for fluid and gas transfer, identified by measuring the thread diameter and subtracting 1/4". While NPT connections provide a metal-to-metal sealing design ideal for single assembly applications, they are not recommended for frequent disassembly due to potential thread wear. The Series 2705 bulkhead adapters enhance system performance and are an excellent choice for professionals seeking reliable hydraulic solutions.
