Our Series 6400-L-O Straight Male JIC x Male ORB hydraulic long adapters are essential components designed for efficient fluid connections in hydraulic systems, featuring a longer length than the standard Series 6400-O. Made from durable carbon steel, these adapters consist of a male JIC (Joint Industry Council) end on one side and a male ORB (SAE Straight Thread O-ring Boss) end on the other. 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 achieved through contact between the male flared seat and the female coned seat, forming a robust mechanical connection. The ORB end enhances leak prevention in medium and high-pressure applications by utilizing a straight UNF thread with an O-ring. The female port is designed with a machined surface and a chamfer for the O-ring, ensuring a secure, leak-tight seal when the connections are mated. These long adapters are ideal for applications requiring additional reach while maintaining the efficiency and reliability that professionals in the fluid power industry demand.
