Question by: Norm R on Jul 4, 2025, 9:08 PM

What kind of plating does this fitting have? I need something that can hold up.

Dura-Kote plating gives this fitting some serious corrosion resistance, which is what you want for long-term reliability.

fitting says 4-wire spiral, does that mean it's only gonna work with spiral hose or can it go on other types too?

Answer by: Customer Support on Jun 22, 2025, 2:35 PM

Four-wire spiral fittings are matched to four-wire spiral hose constructions. The dash size here is -12, so you'd pair it with a -12 four-wire spiral hose. Trying to crimp it onto a different hose type or a different dash size isn't something this fitting is built for, and you'd risk a bad assembly that won't hold up under pressure.
