The MIDLAND INDUSTRIES 17031616 is a 45-degree adapter elbow fitting designed to transition a 1-inch Male JIC connection to a 1-inch Code 61 flange connection in steel hydraulic systems. Built from steel with a 1-5/16-12 thread, it handles a maximum operating pressure of 3000 psi, making it suitable for medium- to high-pressure hydraulic circuits. The elbow configuration allows direction changes within tight plumbing runs without the need for additional fittings or fabricated bends. Hydraulic system installers and maintenance technicians working on industrial or mobile equipment will find this fitting straightforward to source and install as a direct hardware replacement or new-build component.
This fitting belongs to the 1703 Series, which covers Male JIC to Code 61 Flange 45-degree elbow configurations in steel. It is intended for hydraulic plumbing applications where a JIC-threaded line must connect to a Code 61 flange port at a 45-degree angle. Typical installations include mobile hydraulic equipment, industrial machinery, and fluid power systems that operate within the 3000 psi pressure rating. The Code 61 flange end conforms to standard SAE flange port dimensions for that pressure class.
Designed as an OEM-style steel hydraulic adapter for systems utilizing 1-inch Male JIC threaded lines connecting to 1-inch Code 61 SAE flange ports in medium- to high-pressure hydraulic circuits up to 3000 psi.
Installation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect mating surfaces and threads for damage before assembly, and use appropriate thread sealant or seating practices per the fitting manufacturer guidelines. Follow applicable industry standards for hydraulic piping and fittings during installation.
