Our Series FS6504 Straight Male JIC x Female ORFS Swivel hydraulic adapters are essential components designed to ensure reliable fluid transfer in hydraulic systems. Constructed from durable carbon steel, these adapters feature a male JIC end that connects to a female ORFS 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 robustness. The seal is achieved by establishing contact between the male flared and female coned seat, creating a strong mechanical connection. ORFS, or O-ring Face Seal fittings, are designed with an O-ring seated in a groove at the face of the fitting, providing an elastomeric seal that enhances leak resistance. Made to SAE J1453 standards, ORFS connections typically incorporate Buna-N or Viton, 90 Durometer O-rings. The seal is formed when the O-ring compresses against the flat face of the mating fitting or tube upon tightening. This innovative design ensures a secure connection while minimizing the risk of leaks, making Series FS6504 adapters a preferred choice for professionals in the fluid power industry seeking dependable hydraulic solutions.
