Our Series FS6403 Straight Male ORFS x Male JIC hydraulic adapters are crucial components designed to ensure secure and efficient fluid connections in hydraulic systems. Made from durable carbon steel, these adapters feature a male ORFS (O-ring Face Seal) end on one side and a male JIC (Joint Industry Council) end on the other. 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 reliability. The seal is created by contact between the male flared seat and the female coned seat, forming a strong mechanical connection. The ORFS fitting incorporates an O-ring at the face, which, as per SAE J1453 standards, provides an elastomeric seal. The O-ring compresses between the flat face of the fitting and the mating ORFS fitting or formed tube when the connection is tightened, ensuring a leak-tight seal. These adapters are ideal for professionals seeking dependable and efficient solutions for hydraulic applications in demanding environments.
