Question by: Keith R on Aug 9, 2025, 11:13 AM

Will this fitting hold up if it's constantly exposed to the elements and some pretty harsh chemicals?

Dura-Kote plating gives this Eaton Aeroquip fitting enhanced corrosion resistance, which should extend its life even when dealing with harsh conditions.

Question by: Danny E on Jun 10, 2025, 11:43 AM

fitting's got Dura-Kote plating on it -- how well does that actually hold up against rust and corrosion out in the field?

Answer by: Customer Support on Jun 11, 2025, 5:20 PM

Dura-Kote is a corrosion-resistant plating applied specifically to extend the service life of the fitting in harsh or exposed environments. Carbon steel on its own is vulnerable to rust, but the Dura-Kote finish gives it meaningful protection against moisture and corrosive conditions. That's a big part of why Eaton Aeroquip uses it on assemblies like this one where long-term uptime matters.
