Question by: Connie F on Dec 17, 2025, 6:17 AM

Will this fitting hold up if I'm running hydraulic fluid through it pretty much non-stop?

Answer by: Customer Support on Dec 18, 2025, 7:57 AM

Dura-Kote plating is included for corrosion resistance, which helps extend the fitting's life even with continuous use.

trying to swap out a fitting on a -16 hose, is this one actually made for that dash size?

Answer by: Customer Support on Feb 26, 2026, 12:13 PM

It is built around a -16 hose dash size, so it matches hose assemblies that call for a -16 in the Eaton Aeroquip 4S Series crimp style.

fitting says it don't need any mandrels or adjustments during install, that accurate for the 4SA16PS16?

Answer by: Customer Support on May 8, 2025, 6:43 AM

Correct on that. The design eliminates the need for mandrels or any pre-installation adjustments, so you're working with a straightforward crimp process. That's one of the things that makes this fitting practical for production environments where you want consistent results without extra steps.
