08 STANDARD NUT

Description & Features

Manufactured from straight steel, this JIC long tube nut is designed for 1/2" OD tube connections and threads at 3/4-16 UNF in conformance with SAE J514. The 08 Standard Nut features a 0.875" hex and an overall length of 1.280", making it well-suited for standard hydraulic line assemblies where a reliable 37-degree flare connection is required.

Part of Brennan Industries' 0304 series, this fitting is a common choice for hydraulic circuits that demand consistent sealing performance at JIC connections. The long nut configuration provides additional thread engagement compared to standard-length alternatives, which can be advantageous in applications where tube alignment or assembly access is a consideration. California residents should note that this product carries a Proposition 65 warning.

Got a hydraulic line running 1/2" OD tube and need a JIC nut to finish the connection. This the right one for that?

Answer by: Customer Support on Jul 8, 2025, 10:10 AM

For 1/2" OD tube with a JIC 37-degree flare connection, this is the correct fit. It threads at 3/4-16 UNF per SAE J514, which is the standard spec for that tube size in JIC assemblies. The long nut configuration also gives you a bit more thread engagement than a standard-length nut, which can help when you're working in tighter spots or need a little extra stability on the connection.
