Our Series 2764-LN Straight Male ORB x Male JIC hydraulic adapters are essential components designed to ensure reliable connections in hydraulic systems. Made from durable carbon steel, these adapters feature a male ORB (SAE Straight Thread O-ring Boss) end that connects seamlessly to a male JIC (Joint Industry Council) fitting. JIC 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 dependable performance. The seal is achieved by establishing contact between the male flared seat and the female coned seat, creating a robust mechanical connection. The ORB connection utilizes a straight UNF thread with an O-ring, providing an effective leak prevention method for medium and high-pressure applications, as recommended by the National Fire Protection Association (N.F.P.A.). The female port features a machined surface that ensures a smooth, flat seating area for the O-ring, which compresses into the chamfer when the connections are mated, resulting in a leak-tight seal. These adapters enhance system reliability and efficiency, making them an ideal choice for professionals in the fluid power industry.
