Danfoss / Eaton Coupling

Description & Features

Designed to adapt standard steel brake lines to the varying port sizes found in dual master cylinders, this Danfoss / Eaton Coupling is a straight adapter with a UNF female to metric male internal connection type. The 3/8-inch male metric end and 0.125-inch tube ID make it well-suited for hydraulic brake line configurations requiring a precise size transition between mismatched port standards.

Finished in nickel-plated brass with Eaton Weatherhead's Dura-Kote plating, the adapter provides reliable corrosion resistance in demanding hydraulic environments. Operating pressures exceed SAE standards, and the broad range of available styles within this product line supports flexible integration across a variety of hydraulic brake system configurations.

Question by: Earl Y on Feb 6, 2026, 7:58 PM

Got a dual master cylinder with mismatched port sizes, will this adapter handle the transition from a standard steel brake line over to the metric side without needing extra fittings?

Answer by: Customer Support on Feb 8, 2026, 7:39 PM

That's what it's built for. The UNF female end connects to your standard steel brake line, and the 3/8-inch metric male end ties into the metric port on the dual master cylinder. One piece, straight through, no additional fittings needed to bridge that size gap. The 0.125-inch tube ID keeps the internal flow path consistent through the transition, so you're not introducing a restriction in the line.
