Eaton 12Z-S70-BG Female Ors Swivel Fitting 12mm Steel

Product Description

The EATON 12Z-S70-BG is a female ORS swivel fitting designed for hydraulic hose assemblies. It features an O-ring face seal (ORS) connection with a swivel design that allows rotation during installation, reducing hose twist and simplifying routing. Built from steel with a FOR-SEAL shaft type, this fitting accepts a 1-inch hose diameter and threads onto a 1-14 straight thread port. It is used by hydraulic technicians and fluid power specialists assembling or repairing hydraulic lines on mobile equipment, industrial machinery, and similar high-pressure systems. The 1-1/8-inch hex size accommodates standard open-end or combination wrenches.

This fitting is suited for hydraulic systems requiring a leak-resistant ORS face seal connection at the port end. The swivel feature is especially useful in tight installations where hose orientation must be set without inducing torsional stress on the hose. Typical applications include agricultural equipment, construction machinery, and industrial hydraulic power units where steel fittings and straight-thread ORS ports are specified. The 12mm hose size designation follows the standard hose series classification used in fluid power assemblies.

Compatibility

Designed as an OEM-style replacement swivel fitting for hydraulic hose assemblies using 12mm hose with a 1-14 straight thread ORS port connection.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and drain the hydraulic system fully before removing or installing any fitting. Inspect the O-ring sealing surface on both the fitting and the port for nicks or contamination before assembly. Do not overtighten; use the hex flats and a torque wrench per the system designer or equipment manufacturer specifications, as no torque value is specified for this part in the available data.
