Danfoss / Eaton Coupling

Description & Features

Designed for air brake systems, this brass straight adapter connects a 1/4 in. UNF female thread to a 0.5313 in. hose or tube female end, making it a reliable choice for nylon tubing installations where operating temperatures remain below +200°F and exposure to battery acid is not a factor. The Danfoss / Eaton Coupling carries a minimum working temperature rating of -40°F, supporting use in cold-weather environments without performance compromise.

Constructed from brass with Dura-Kote plating, the fitting provides strong corrosion resistance suited to demanding service conditions. Operating pressures exceed SAE standards, and the design is part of a broad family of straight adapter styles, offering flexibility when configuring air brake circuit connections. Net weight is approximately 1.1 lb with a product width of 0.69 in.

Question by: Dwayne G on Sep 11, 2025, 7:58 PM
Will this Eaton coupling hold up if it gets splashed with battery acid sometimes?
Answer by: Customer Support on Sep 13, 2025, 8:57 AM
The description says this fitting isn't recommended where battery acid can drip on the tubing, so I wouldn't risk it.
