#4 MJIC X #8 FP

Description & Features

Rated to 5,000 PSI dynamic pressure, this straight steel adapter from Brennan Industries connects a #4 Male JIC SAE 37° Flare (7/16-20, per SAE J514) to a #8 Female NPTF (1/2-14, per SAE J476) in a single compact fitting. The #4 MJIC x #8 FP is manufactured from straight steel and carries a Prop 65 warning for California residents.

The mismatched thread sizes make this fitting well suited for hydraulic circuits where a JIC line-side connection must terminate into an NPTF port, bridging two common thread standards without additional adapters. Overall length is 1.680 mm, keeping installation compact within tight assemblies.

So, this adapter goes from a smaller JIC to a bigger NPTF, right? Just wanna make sure I'm understanding that correctly before I order.

You've got it. This straight steel adapter connects a #4 Male JIC (SAE 37° Flare) to a #8 Female NPTF, allowing you to adapt between the two thread standards in your hydraulic system. It's a pretty compact way to bridge those different sizes.
