Question by: Warren B on Sep 22, 2025, 6:58 PM

what's the corrosion protection like on these fittings? running equipment that sees a lot of moisture and i don't want stuff rusting out on me

Answer by: Customer Support on Sep 24, 2025, 6:17 AM

Eaton Aeroquip put a Dura-Kote plating on these fittings specifically to hold up against corrosion. Carbon steel on its own would be vulnerable in wet or harsh conditions, but that plating adds a meaningful layer of protection that makes them more suitable for demanding environments where moisture is a real concern.
