Question by: Jean B on Aug 9, 2025, 7:44 PM

What kind of corrosion resistance does this tube nut have?

Answer by: Customer Support on Aug 11, 2025, 7:59 AM

This Danfoss/Eaton Weatherhead tube nut features Dura-Kote plating, which gives it excellent corrosion resistance.

Question by: Harvey M on Dec 15, 2025, 6:22 PM

what's the coating on this nut, and does it hold up decent in wet or outdoor conditions?

Answer by: Customer Support on Dec 17, 2025, 9:51 AM

Carbon steel tube nuts like this one get a zinc clear trivalent chromate finish, which is what Eaton calls their Dura-Kote plating. That treatment gives it better corrosion resistance than a plain steel part, so it holds up reasonably well when exposed to moisture or outdoor environments. It's not a stainless piece, but the plating does meaningful work keeping rust from taking hold under normal service conditions.

got a Weatherhead 105x setup, is the 105X5 nut the right spare part or am i mixing series

Answer by: Customer Support on Aug 9, 2025, 10:58 AM

For replacement purposes, 105X5 is a 105x Series spare part tube nut under the Weatherhead name, so it matches that 105x family rather than a different series.
