The MIDLAND INDUSTRIES D7405-L06-06 is a steel DIN-to-female BSPP adapter designed for hydraulic tube and line assemblies. It connects an L06 metric bite-type fitting end (M12 x 1.5 thread) to a 3/8-19 female BSPP port, conforming to DIN 2353 and ISO 8434-1 dimensional standards. The body is steel with a trivalent chromium zinc-plated finish for corrosion resistance. Rated to 31.5 MPa anticipated working pressure, this fitting is sized for L06 (light series) metric compression tube connections and is installed by hydraulic system technicians and fluid power mechanics in industrial and mobile equipment applications.
This adapter is used where metric bite-type hydraulic lines must terminate into a BSPP-ported manifold, valve, cylinder, or component. The L06 metric bite-type end grips the tube ferrule on assembly, while the female BSPP end threads directly onto a male BSPP port. Typical installation environments include mobile hydraulic machinery, industrial presses, and OEM fluid power systems requiring cross-standard connection between DIN metric compression lines and BSPP-threaded components.
Designed as an OEM-style replacement or service fitting for hydraulic systems requiring a DIN 2353 L06 metric bite-type connection to a 3/8-19 female BSPP port, per ISO 8434-1 standards.
Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. Inspect threads and seating surfaces for damage before assembly, and apply appropriate thread sealant or BSPP sealing method per system requirements. Do not over-tighten; follow the fitting manufacturer and system designer torque guidance for the tube size and pressure class in use.
