Our Series 2705 Straight Male JIC x Female NPT Rigid Bulkhead hydraulic adapters are crucial components designed for efficient fluid transfer in hydraulic systems. Constructed from robust carbon steel, these adapters feature a male JIC end that connects to a female NPT fitting. JIC fittings, as 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 created by ensuring contact between the male flared and female coned seat, establishing a strong mechanical connection. Additionally, NPT (National Pipe Taper) connections utilize tapered threads to effectively seal pipes for fluid and gas transfer. The nominal pipe size can be identified by measuring the thread diameter and subtracting 1/4". Bulkhead adapters allow for connections to be made through a wall or panel, providing a secure and leak-proof passage for fluids while saving space and maintaining structural integrity. While NPT connections offer 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 adapters enhance system performance and are an excellent choice for professionals seeking dependable hydraulic solutions.
