Danfoss / Eaton Brass Adapter

Description & Features

A straight brass adapter designed for NPTF female to hose/tube female connections, the Danfoss / Eaton Brass Adapter from Aeroquip provides reliable joining in demanding hydraulic and industrial fluid systems. With a 1/4" NPTF female end on one side and a 1/4" line/hose/tube female end on the other, it handles a wide range of connection scenarios where dissimilar end types need to be bridged in a compact, inline configuration.

Manufactured from brass with Dura-Kote plating, this adapter offers strong resistance to corrosion in challenging service environments. It is rated for operating pressures above SAE standards, making it well-suited for higher-pressure hydraulic circuits. The 0.562" hex and 0.69" width allow for straightforward installation with standard tooling.

Product Questions & Answers (1)

Question by: Dean B on Sep 5, 2025, 7:50 AM

Will this adapter work okay with standard hydraulic pressures, or is it more for lower-pressure stuff?

Answer by: Customer Support on Sep 6, 2025, 1:07 PM

Dura-Kote plating gives this brass adapter superior corrosion resistance and the higher operating pressures exceed SAE standards, so it will work in standard hydraulic circuits with confidence.
