Eaton 12Z-12L-BG Hydraulic Hose Fitting Jis 30 Flare Swivel

Product Description

The EATON 12Z-12L-BG is a female JIS 30 flare swivel straight hydraulic hose fitting machined from steel. It connects a 12 mm (3/4 inch) hose end to a G 3/4-14 threaded port using a JIS 30-degree flare sealing interface. The swivel design allows the fitting to rotate during assembly, reducing hose twist and simplifying routing in tight spaces. At 0.57 pounds and compact dimensions, it is a direct-install component suited for hydraulic line assemblies on mobile equipment, industrial machinery, and related fluid-power systems. Installation is typically performed by hydraulic technicians and maintenance mechanics.

This fitting is used in hydraulic systems that require a female JIS 30 flare connection at the hose end and a straight G 3/4-14 port connection. The straight configuration is appropriate for inline routing where no angle offset is needed. It is commonly installed in mobile hydraulic circuits, construction and agricultural equipment, and industrial hydraulic power units where JIS-standard fittings are specified. The steel construction supports the pressure demands typical of these applications.

Key Features

• Female JIS 30 flare swivel interface provides a leak-resistant seal at the hose end
• Straight configuration for direct inline hydraulic line connections
• Swivel design reduces hose twist during assembly and tightening
• G 3/4-14 port thread accommodates standard BSP-style threaded ports
• Steel construction for durability in high-pressure hydraulic service
• Compact form factor at 2.88 inches length and 1.56 inches width

Compatibility

Designed as an OEM-style replacement hydraulic hose fitting for systems specifying a 12 mm hose size with a G 3/4-14 port thread and a JIS 30 flare swivel straight end configuration.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and fully relieve hydraulic system pressure before removing or installing any fittings. Inspect mating port threads and flare seating surfaces for damage before assembly. Do not over-tighten; follow the fitting manufacturer and equipment OEM torque guidelines for the applicable port and hose end type.
