Midland Industries 240684 Jic Reducer Expander Steel Adapter

Product Description

The MIDLAND INDUSTRIES 240684 is a steel JIC reducer/expander fitting designed to connect a 1/2-inch female JIC port to a 1/4-inch male JIC port within hydraulic plumbing systems. It carries a 3/4-16 thread on the female end and a 7/16-20 thread on the male end, conforming to standard JIC 37-degree flare geometry. At 0.115 pounds, the fitting is compact and sized for tight hydraulic assemblies. It is used by hydraulic system technicians, mobile equipment mechanics, and industrial maintenance professionals who need to step down or step up line sizes without adding extra adapters in a run.

This fitting is suited for hydraulic pressure lines in mobile equipment, industrial machinery, and fluid power systems where two JIC-threaded components of different line sizes must be joined. The 2406 Series designation places it within a standardized family of steel JIC adapters, making it a straightforward selection for spec-to-spec replacements or new hydraulic plumbing builds. It is appropriate for both shop fabrication and field service work where JIC fittings are the specified connection standard.

Key Features

• Reduces or expands between 1/2-inch female JIC and 1/4-inch male JIC in a single fitting
• 3/4-16 female thread x 7/16-20 male thread for standard JIC 37-degree flare compatibility
• Steel construction for durability in hydraulic pressure line applications
• Compact footprint: 1.35 inches long, 1 inch wide, 0.85 inches tall
• Lightweight at 0.115 pounds, minimizing load in tight plumbing runs
• Part of the 2406 Series steel JIC adapter family for consistent spec conformance

Compatibility

Designed as an OEM-style replacement or new-build component for hydraulic systems using standard JIC 37-degree flare fittings where a 1/2-inch female JIC to 1/4-inch male JIC transition is required.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanic familiar with JIC flare fittings. Depressurize and bleed the hydraulic system fully before removing or installing any fittings. Hand-tighten the fitting first to confirm thread engagement, then torque to the value specified in the equipment service manual for the applicable line size. Inspect the 37-degree flare seats on mating components for damage before assembly to prevent leaks.
