The 1JG9-OG Series Adjustable 90° JIC Male 74° Cone / BSP Male O-Ring Seal Elbow Adapter is a right-angle hydraulic fitting designed to connect a JIC female 74° flare connection with a compatible BSP threaded port.
The E end features a JIC male 74° cone connection, while the F end uses a BSP parallel male thread with an O-ring sealing arrangement and an adjustable stud-end configuration. According to the supplied product drawing, the F thread end is intended for use with a compatible ISO 1179-1 port.

The 90° elbow design changes the direction of the hydraulic connection, helping accommodate pipe routing in installations with limited space. Its adjustable configuration allows the elbow orientation to be set during installation according to the fitting design and assembly requirements.
The series includes multiple combinations of JIC inch threads and BSP parallel threads, with E-end sizes ranging from 7/16"-20 to 1-7/8"-12 and F-end sizes ranging from G1/8 to G1-1/2, according to the supplied dimensional table.
Each model has its own part number, O-ring designation, and installation dimensions. Selecting the correct configuration requires checking the thread specifications, mating port, sealing arrangement, and available installation space.
The right-angle body provides a 90° change in connection direction, making it suitable for hydraulic layouts where a straight adapter would not provide the required routing direction.
The E end features a JIC male 74° cone connection. It is designed to mate with a compatible JIC female 74° flare fitting, subject to matching thread and connection specifications.
The F end uses a BSP parallel male thread with an O-ring sealing arrangement. The supplied drawing specifies compatibility with an ISO 1179-1 port. The correct sealing interface and O-ring specification must be verified for the selected model.
The adjustable configuration allows the elbow orientation to be positioned during installation. Correct positioning and tightening must follow the fitting's design requirements to ensure compatibility with the mating port.
The series provides a range of JIC and BSP thread combinations, allowing buyers to select a suitable adapter for different compatible hydraulic connection interfaces.
