    SAE O-Ring Boss (ORB) threaded fittings are exemplary for managing leaks in medium to high-pressure scenarios. Although SAE ORB and JIC 37° fittings share identical straight threads, they differ significantly in their sealing mechanisms. JIC fittings achieve a seal through metal-to-metal contact, while SAE ORB fittings rely on an O-ring for sealing. O-ring seals are superior in preventing leaks, as the sealing occurs at the O-ring rather than the threads. This unique feature makes SAE ORB fittings reusable, enhancing their practicality and efficiency in fluid power applications.

    ORB & ORFS Fittings

    What Are ORB Fittings?

    Known as O-ring boss (ORB) fittings, these components meet SAE J1926 standard. This standard outlines the specifications for both male and female parts, incorporating the Unified Thread Standard (UNF/ASME B 1.1) for the male threads and a specific groove for an O-ring(NBR or FKM Viton). The female part features a seat or chamfer that initiates the threading. Upon connection, the O-ring, situated between the male and female seats, compresses to create an exceptionally tight seal, effectively compensating for any dimensional discrepancies.

    ORB fittings are essential in systems requiring robust seals under high pressure, such as in hydraulic and automotive applications. To accommodate the variety of global standards for fluid conveyance, ORB fittings are often designed to interface with other types of connections like NPT, NPS, AN, or JIS. They are typically manufactured from high-strength carbon or stainless steel to endure the demands of high-pressure environments.

    JIC Fittings

    What Are JIC Fittings?

    JIC (Joint Industry Council) fittings, specified by SAE J514, feature a 37-degree flare seating surface and parallel threads for compression connections. These fittings, often made from nickel alloys, brass, carbon, and stainless steel, are prevalent in fluid power systems. Both male and female parts possess 37-degree seats, with the seal formed through contact between the male flare and the female coned seat, creating a mechanical connection. A complete tubing assembly comprises three elements: the fitting, flare nut, and sleeve.
