Midland Industries 2406126 Jic Reducer Expander Steel

Product Description

The MIDLAND INDUSTRIES 2406126 is a steel JIC reducer/expander fitting designed to connect a 3/4-inch female JIC port to a 3/8-inch male JIC port within hydraulic fluid lines. It uses a 1-1/16-12 female thread on one end and a 9/16-18 male thread on the other, conforming to standard 37-degree JIC flare geometry. This adapter allows technicians to step down or step up line sizes at a connection point without splicing hose or modifying existing components. It is a solid steel fitting suited for high-pressure hydraulic applications. Hydraulic technicians and fluid power mechanics are the primary installers.

The 2406126 is used in hydraulic systems where two JIC lines of differing sizes must be joined at a single connection point. Common install scenarios include mobile equipment, industrial machinery, and hydraulic power units where line routing requires a size transition. The compact body measures approximately 1.4 inches in length and 1.35 inches in width, making it practical in tight plumbing layouts. It belongs to the MIDLAND INDUSTRIES 2406 Series of female JIC to male JIC reducer/expander adapters.

Key Features

• Reduces or expands between 3/4-inch female JIC and 3/8-inch male JIC in a single fitting
• 37-degree JIC flare thread form on both ends for leak-resistant sealing
• Threads: 1-1/16-12 female JIC x 9/16-18 male JIC
• Solid steel construction for high-pressure hydraulic service
• Compact body - approximately 1.4 inches long - fits in confined plumbing spaces
• Part of the 2406 Series, designed as a direct OEM-style replacement or new-installation adapter

Compatibility

Designed for use in hydraulic systems requiring a 3/4-inch female JIC to 3/8-inch male JIC size transition. Suitable for any application using standard 37-degree JIC flare fittings at the specified thread sizes.

Installation Notes

Hydraulic technicians should depressurize and fully bleed the hydraulic circuit before removing or installing any fitting. JIC flare fittings seal on the 37-degree metal-to-metal flare seat - use a backup wrench on the mating port to avoid twisting hoses or damaging upstream components. Do not use thread sealant tape on JIC fittings, as the flare seat provides the seal. Inspect both mating flare seats for nicks or damage before torquing to assembly.
