Midland Industries 70021012 Mjic X Male Bspp Hydraulic Adapter

Product Description

The MIDLAND INDUSTRIES 70021012 is a steel hydraulic adapter designed to connect a 5/8-inch MJIC (Male JIC 37-degree flare) fitting to a 3/4-inch Male BSPP (British Standard Parallel Pipe) port. Thread dimensions are 7/8-14 on the JIC side and 3/4-14 on the BSPP side. Rated to 3500 psi maximum operating pressure and 375 degrees F, this adapter handles demanding hydraulic system conditions. It is used by hydraulic technicians and fluid power professionals to bridge JIC and BSPP connection standards in steel-line assemblies.

This adapter fits residential and commercial hydraulic applications where North American JIC flare lines must interface with BSPP-threaded ports common on imported machinery, European-spec equipment, and industrial hydraulic components. Typical installations include mobile hydraulic systems, power units, and industrial machinery requiring a secure, pressure-rated transition between JIC and BSPP standards. Part of Midland's 7012 Series of MJIC-to-BSPP adapters, it is suited for systems running petroleum-based or compatible hydraulic fluids within the specified pressure and temperature limits.

Key Features

• 3500 psi maximum operating pressure for high-demand hydraulic systems
• 375 degrees F maximum operating temperature rating
• 5/8-inch MJIC (7/8-14 thread) to 3/4-inch Male BSPP (3/4-14 thread) configuration
• Steel construction for durability in hydraulic line service
• Part of the 7012 Series for consistent cross-compatibility within the Midland BSPP adapter line

Compatibility

Designed as an OEM-style hydraulic adapter for systems requiring a 5/8-inch MJIC to 3/4-inch Male BSPP transition. Compatible with hydraulic assemblies operating within the 3500 psi and 375 degrees F ratings and using fluids compatible with steel fittings.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power professional. Depressurize and bleed the hydraulic system fully before removing or installing any fittings. Apply thread sealant appropriate for BSPP parallel threads, as BSPP connections rely on a sealing face or O-ring rather than thread taper for pressure integrity. Do not exceed the 3500 psi pressure rating or 375 degrees F temperature limit in service.
