Question by: Dean C on Aug 2, 2025, 6:00 AM

Will this fitting hold up in a hydraulic system that sees a lot of vibration?

Answer by: Customer Support on Aug 3, 2025, 3:20 PM

Dura-Kote plating provides excellent corrosion resistance, while the innovative design ensures both performance and maximum uptime, which should hold up well under normal operating conditions.

trying to swap a fitting on a -4 hose, is this one set up for a 1/4 NPSM female end?

Answer by: Customer Support on Jan 12, 2026, 3:42 PM

It matches a -4 hose dash size and a 0.25 inch female NPSM end connection, so it lines up with assemblies needing that female NPSM interface.

what's the corrosion protection like on this fitting? running it in a pretty wet environment and had issues with rust on other brands

Answer by: Customer Support on Jul 20, 2025, 6:45 PM

Carbon steel fittings can be hit or miss in wet conditions, but this one carries Dura-Kote plating specifically for corrosion resistance. It's built to hold up in demanding operational environments, so moisture exposure was clearly part of the design consideration. That plating is what separates it from bare steel options that tend to rust out faster.
