BRENNAN 8JIC - 18

Description & Features

A straight steel hydraulic adapter connecting a 3/4-16 Male JIC SAE 37° Flare (SAE J514) end to an M18x1.5 Male Metric (ISO 9974) end, the Brennan 8JIC - 18 is designed for applications requiring a reliable transition between JIC and metric threaded connections. The straight configuration keeps the assembly compact, and the steel construction suits standard hydraulic line environments where durability under pressure cycling is expected.

Part of Brennan Industries' Series 7005, this adapter is built to recognized industry standards on both ends, making it well-suited for hydraulic circuits that combine SAE and metric components, common in mobile equipment, industrial machinery, and imported hydraulic systems. Drill sizes of 9.9 mm and 11.1 mm correspond to the respective thread ends and are consistent with standard port and fitting dimensions for this size range.

Will this here fitting work to join a JIC flared line to a metric line?
Answer by: Customer Support on Feb 16, 2026, 5:31 PM
Designed for transitioning between JIC and metric threaded connections, this adapter should work for that. It's meant for hydraulic circuits that use both SAE and metric parts, which is common in machinery and imported systems.
