brass fitting gonna hold up alright in a hydraulic line, or is this more of a pneumatic-only deal?

Question by: Tony T on Jan 6, 2026, 12:09 PM

Brass works fine for both hydraulic and pneumatic applications, and that's exactly what this fitting is rated for. It's also suited for instrumentation systems, so it sees real use across a range of line pressures. The Dura-Kote plating adds a layer of corrosion resistance beyond what bare brass typically offers, which helps in environments where moisture or mild chemical exposure is a concern.
