12MJ-08MBSPP ED STRAIGHT ED CAPTIVE SEAL

Description & Features

Manufactured by Brennan Industries, this straight end captive seal fitting connects a 12 MJ (1-3/16"-12 JIC male) end to a 08 MBSPP (1/2" male British Standard Parallel Pipe) thread. The captive seal design retains the O-ring within the fitting end, preventing displacement during assembly and supporting a reliable, leak-resistant connection in hydraulic circuit applications.

The 12MJ-08MBSPP ED Straight ED Captive Seal is suited for use where JIC and BSPP thread standards must be joined in a straight-line configuration. This fitting type is commonly used in mobile and industrial hydraulic systems requiring compatibility between SAE and metric or international thread standards.

So this fitting connects two different thread types, right? What exactly are they?

This fitting adapts a 1-3/16"-12 JIC male end to a 1/2" male British Standard Parallel Pipe thread. It's designed to bridge the gap between JIC and BSPP thread standards.
