12MJ-12MBSPP ED STRAIGHT ED CAPTIVE SEAL

Description & Features

Manufactured by Brennan Industries, this straight-configuration hydraulic fitting connects a 1-1/16-12 UN male JIC (37° flare) end to a 1-5/8-12 UN male BSPP end with an end-to-end captive seal design. The captive seal configuration provides a reliable, leak-resistant connection without requiring additional sealing compounds, making it well suited for hydraulic circuits where fluid integrity is critical.

The 12MJ-12MBSPP ED Straight ED Captive Seal is appropriate for use in medium- to high-pressure hydraulic systems requiring a transition between JIC and BSPP thread standards. Straight-body construction keeps the fitting compact within tight assemblies, and the end-to-end design ensures consistent sealing contact across both connection points.

Will this fitting work to connect a JIC to a BSPP setup without any leaks? Gotta make sure it's tight.

This fitting includes a captive seal design intended to provide a reliable, leak-resistant connection, so you shouldn't need any additional sealants.
