Question by: Frank H on Jan 26, 2026, 7:35 AM

Does this fitting work with a -16 hose on a 4-wire spiral assembly, or is it sized different than what I'm thinking?

Answer by: Customer Support on Jan 27, 2026, 6:37 PM

For 4-wire spiral hose assemblies, the dash size on this fitting is -16, so if your hose is spec'd at -16, you're in the right place. The end connection is a female ORS swivel, and the hex comes in at 1.875 inches. Carbon steel construction with Dura-Kote plating keeps corrosion from becoming a problem over time, which matters a lot when you're running a system that needs to stay tight and dependable between service intervals.

Will this fitting hold up to a good bit of vibration in heavy equipment, or should I be looking at something else?

Dura-Kote plating on this Eaton Aeroquip fitting provides superior corrosion resistance, and the fitting is system-engineered to extend hose assembly life, which should help it hold up well to vibration.
