Danfoss / Eaton Coupling

Description & Features

Designed for compressed air and pneumatic applications, this brass straight adapter connects a 3/8 in. NPTF female thread to a 1/4 in. push-to-connect fitting in a single inline configuration. The Danfoss / Eaton Coupling is constructed from brass and finished with Dura-Kote plating, which provides strong resistance to corrosion in demanding service environments.

Operating pressures exceed SAE standards, making this adapter suitable for higher-pressure pneumatic systems. The push-to-connect end simplifies installation without requiring additional tools or fittings, while the NPTF thread end ensures a reliable, pressure-tight mechanical seal. This fitting is part of a broad product family offering hundreds of configuration styles, supporting flexible system design across a wide range of industrial pneumatic applications.
