#20 FJ (RIGID) X #8 MJ ST.

Description & Features

A rigid straight reducer fitting designed to connect a #20 Female JIC to a #8 Male JIC thread, the #20 FJ (Rigid) X #8 MJ ST. is manufactured from straight steel and built to SAE J514 specifications on both ends. The female end carries a 1-5/8-12 thread with an SAE 37-degree flare seat, while the male end is threaded 3/4-16 with a matching 37-degree flare configuration, making this fitting well-suited for hydraulic line assemblies that require a reduction between two JIC connections.

At 1.840 inches overall length, this one-piece rigid fitting provides a compact, fixed-angle solution where swivel movement is not needed. Manufactured by Brennan Industries, it conforms to SAE J514 on both thread ends, supporting consistent compatibility across standard hydraulic circuit components. California residents should note this product is subject to Prop 65 requirements.
