Description & Features

Manufactured from straight steel, the #2 MJ X #4 MP ST. is a hydraulic adapter fitting rated to 6,000 PSI maximum dynamic pressure, making it well-suited for demanding fluid power applications. It connects a Male JIC SAE 37-degree flare thread (5/16-24, per SAE J514) on one end to a Male NPTF thread (1/4-18, per SAE J476) on the other, allowing direct adaptation between these two common thread standards in a single inline fitting.

Part of the Brennan Industries Series 2404, this straight configuration keeps the connection compact with an overall length of 1.330 mm. California residents should note that this product is subject to Proposition 65 warnings.

Reckon this adapter would hold up okay on a hydraulic system pushing close to that 6000 PSI rating?

Rated to a maximum dynamic pressure of 6,000 PSI, this adapter should indeed be suitable for systems operating near that pressure.
