Danfoss / Eaton Aeroquip 6-Wire Spiral TTC Fitting

CAT flange fittings follow the standard code 61 or code 62 four-bolt flange patterns used across most heavy equipment applications. The -16 dash size on this fitting corresponds to a 1-inch nominal hose, so as long as your port and flange head match that sizing, you should have a solid, straight connection without any adapter workarounds.

Carbon steel fittings without good surface protection tend to rust out fast, especially in wet or outdoor environments. The Dura-Kote plating on this one is specifically built to push back against corrosion, so it's not just a coating slapped on for looks. For a -16 flange fitting running spiral hose, that kind of protection matters when you're trying to get real service life out of the assembly rather than swapping it out every season.

Dura-Kote plating on this Eaton Aeroquip fitting offers superior corrosion resistance, and the design is meant to maximize uptime, so it should definitely stand up to the job. It’s engineered to extend the life of the hose assembly too.
