Ask A Question

Description & Features

Manufactured by Brennan Industries, the 08MJ-18MMOR ISO 6149 Straight fitting provides a reliable straight-configuration connection for hydraulic line assemblies requiring ISO 6149 metric port compatibility. The fitting pairs an 08 JIC male end with an 18mm metric O-ring port, making it suited for systems where JIC flare connections interface with ISO 6149-compliant metric ported components.

ISO 6149 ports use an O-ring face seal at the metric thread for leak-resistant performance, a common requirement in mobile hydraulic equipment and industrial machinery. Brennan Industries is a recognized manufacturer of hydraulic fittings and adapters, and this part reflects their standard straight-body adapter configuration.
