Description & Features

Carbon steel construction and Dura-Kote plating make this tube nut a reliable choice for hydraulic connections where corrosion resistance is a priority. Part of the Aeroquip 221000 Series, the Danfoss / Eaton ADP Tube Nut Style A is engineered to meet and exceed SAE pressure standards, supporting higher operating pressures than the baseline specification requires.

The Style A design is one of hundreds of configurations available within the 221000 Series, giving system designers flexibility when matching fittings to specific assembly requirements. Carbon steel construction keeps the fitting well-suited to demanding industrial hydraulic environments where durability under pressure is expected.

reckon this'll hold up alright in a hydraulic system that sees a good bit of vibration and pressure spikes?
Answer by: Customer Support on Jul 20, 2025, 3:48 PM
Dura-Kote plating gives this tube nut enhanced corrosion resistance, and it's been engineered to exceed SAE pressure standards. So it should be a reliable choice, even if your system sees higher-than-normal operating pressures or vibration.
