Designed for general purpose low and medium pressure hydraulic circuits, this carbon steel crimp hose fitting from Eaton Aeroquip features a male straight thread O-ring swivel (ORS) end with a -4 hose dash size and a 7/16-inch thread diameter. The swivel configuration simplifies installation by allowing the fitting to rotate during assembly, reducing hose stress at the connection point.
The Danfoss / Eaton Aeroquip Hose Fitting. Steel Crimp is finished with Dura-Kote plating, providing strong resistance to corrosion in demanding industrial environments. Engineered as part of Eaton Aeroquip's 1A Series crimp system, the fitting is designed to extend hose assembly service life and support consistent performance under normal operating conditions. Where shock hazards are a factor, Eaton recommends using H277 or H435 series hose in place of standard assemblies. Fluid compatibility data is available through Eaton's published documentation for reference during product selection.

fitting rotates during assembly or is it fixed once crimped on?
Answer by: Customer Support on May 26, 2025, 6:47 AM
The swivel is on the male ORS end, so it rotates freely during installation to help you position the hose without twisting it under load. Once everything is tightened down the hose end is crimped and stays put, but that swivel makes a real difference when you're working in a tight spot and need to thread things in without fighting the hose.
