Eaton Aeroquip 900599-24S Hydraulic Plug

The Eaton Aeroquip 900599-24S is a carbon steel hydraulic hose plug built for dash size 24 hose with a 1 1/2 in internal diameter. It uses a 1-7/8-12 thread and meets SAE/JIC 37 degree flare standards. The fitting is rated for 2,000 psi service and is designed for reusable assembly. It suits maintenance teams and machine shops working on high-pressure fluid power systems.

Installation and Common Issues

The plug threads into the matching JIC female port and seals on the 37 degree flare seat without additional sealant. Carbon steel 12L14 or 12L15 construction requires correct torque to avoid stripping the 1-7/8-12 threads. Over-tightening damages the flare seat and causes leaks under 2,000 psi pressure. Reusing the fitting demands inspection of threads and sealing surfaces for wear or corrosion before re-assembly.

Questions about this item

How can I confirm the plug is sealing properly after installation?

After tightening to the correct torque, pressurise the system to its rated 2,000 psi and check the 37-degree JIC flare face for any fluid weep; a dry joint indicates a sound seal.

What comes in the package and which mating parts must be sourced separately?

The box contains the carbon-steel -24 JIC plug only; a matching 1-7/8-12 female swivel nut and the -24 hose assembly are not included and must be ordered separately.
