Straight Male JIC x Male ORB hydraulic adapters are crucial components in hydraulic systems, designed to ensure reliable and leak-free connections. JIC (Joint Industry Council) fittings, defined by SAE J514, feature a 37-degree flare seating surface and parallel threads, commonly found in fluid power systems for their robust performance. The seal is formed by contact between the male flared seat and the female coned seat, creating a strong mechanical connection. In contrast, ORB (SAE Straight Thread O-ring Boss) fittings incorporate an O-ring connection to enhance leak prevention in medium and high-pressure applications, as recommended by the National Fire Protection Association (N.F.P.A.). ORB connections are typically made from carbon steel, nickel-plated carbon, or stainless steel and utilize Buna-N or Viton, 90 Durometer O-rings. The male connection features straight UNF threads with an O-ring, while the female port has a machined surface that provides a smooth, flat sealing area. The leak-tight seal is achieved when the O-ring is compressed into the chamfer during mating, ensuring optimal performance and reliability in demanding hydraulic environments.
