Danfoss / Eaton Coupling

Description & Features

Designed for air brake systems, this brass straight adapter provides a reliable male NPTF connection on one end and a hose/tube connection on the other, with a ½" thread size on the NPTF end and a ¾" connection on the tube end. The Danfoss / Eaton Coupling carries DOT compliance, making it suitable for regulated air brake circuit applications where meeting federal standards is required.

Constructed from brass and finished with Dura-Kote plating, the fitting offers strong corrosion resistance across a wide service temperature range, rated down to -65°F. Operating pressure capability exceeds SAE standards, providing additional margin in demanding air brake environments. The Eaton air brake connector line spans hundreds of fitting styles, supporting design flexibility when specifying components across a system.

Question by: Brett C on Nov 21, 2025, 8:52 AM

Will this here fitting hold up to regular use in an air brake system, or is it more for light duty?

Answer by: Customer Support on Nov 22, 2025, 4:39 PM

This fitting is manufactured from brass with a Dura-Kote plating that provides corrosion resistance and exceeds SAE standards for operating pressure, so it's more than capable of handling demanding air brake environments.
