DANFOSS / EATON

Description & Features

Designed for demanding industrial environments, this carbon steel straight adapter connects SAE 37° male flare fittings to hose, tube, or pipe female ends, with both connection points sized at 0.4375 inches. Built to Aeroquip standards under the Danfoss / Eaton FF1066 Series, the fitting features Dura-Kote plating that provides corrosion resistance above standard industry levels, making it well-suited for exposure to harsh chemicals, moisture, and marine conditions.

Rated for operating pressures exceeding SAE standards, this adapter is appropriate for use across a range of industries including chemical processing, food and beverage processing, pulp and paper, offshore drilling, and marine or military applications. A minimum working temperature of -40° supports cold-environment deployment. Carbon steel construction keeps the fitting durable under mechanical stress, while the swivel reducer design simplifies routing and installation in confined or angled configurations.

Dura-Kote plating gives this fitting enhanced corrosion resistance, so it holds up better than standard fittings when exposed to chemicals, moisture, and marine conditions.
