32MJ-40MP Straight

Ask A Question

Description & Features

A straight-configuration adapter fitting from Brennan Industries, the 32MJ-40MP Straight connects a 2-1/2-12 Male JIC SAE 37-degree flare end (per SAE J514) to a 2-1/2-8 Male NPTF end (per SAE J476). Constructed from straight steel, this fitting is suited for hydraulic systems requiring a reliable transition between JIC flare and NPTF threaded connections at large bore sizes.

Both thread ends are male, making this fitting appropriate for use where female-threaded ports or adapters are present on each side of the connection. The Brennan Series 2404 designation identifies this as part of a standardized adapter family, supporting consistent performance across compatible configurations. California residents should note that this product is subject to Proposition 65 requirements.

Question by: Darryl H on Oct 4, 2025, 4:51 PM
Reckon this would work to connect up some 2-1/2 inch pipes, one with that JIC flare and the other with the NPTF thread?

This straight adapter is made to do just that, joining a 2-1/2-12 Male JIC SAE 37-degree flare end to a 2-1/2-8 Male NPTF end.
