Eaton 06E-666 Female Jic 37 Swivel Fitting 3/8 in Hose

Product Description

The EATON 06E-666 is a female JIC 37-degree swivel fitting designed for use with hydraulic hose assemblies in high-pressure fluid power systems. Manufactured from steel, this Series E fitting connects a 3/8-inch (6 mm) hydraulic hose to a 9/16-18 threaded port. The swivel design allows the hose to be positioned without twisting during installation or service. Rated to a maximum working pressure of 5,000 psi, this fitting is built for demanding hydraulic circuits in mobile, industrial, and stationary equipment. Available in 45-degree elbow, 90-degree elbow, and long drop elbow configurations to suit varied routing requirements.

This fitting is suited for hydraulic hose assembly work in mobile equipment, industrial machinery, and fluid power systems where JIC 37-degree flare connections are specified. It is compatible with SAE-standard hose ends and is appropriate for use in original equipment builds as well as field repair and maintenance applications. Licensed hydraulic technicians and mechanical contractors handling high-pressure hydraulic circuits are the typical installers of this type of fitting.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic system completely before removing or installing any fittings. Use an appropriately sized wrench on the 5/8-inch hex to tighten the fitting; do not use the hose body to torque the connection. Verify thread engagement and inspect for leaks before returning the system to service.
