The Series 6505-SS Straight Male NPT x Female JIC Swivel hydraulic adapters, made from high-quality stainless steel, are vital components designed to create secure and efficient fluid connections in hydraulic systems. Featuring a male NPT (National Pipe Taper) end, these adapters utilize tapered threads to effectively seal pipes for fluid and gas transfer, relying on thread deformation to create a strong metal-to-metal connection. On the other end, the female JIC (Joint Industry Council) fitting, defined by SAE J514, features a 37-degree flare seating surface and parallel threads. The seal is established by contact between the male flared seat and the female coned seat, resulting in a robust mechanical connection. While NPT connections are ideal for single assembly applications, they are not recommended for frequent disassembly due to potential wear on the threads. The nominal pipe size can be determined by measuring the thread diameter and subtracting 1/4". These adapters are perfect for professionals seeking reliable and durable hydraulic solutions across various applications, ensuring optimal performance in demanding environments.
