Ask A Question

Description & Features

Designed for use in hydraulic fluid conveyance systems, the Danfoss / Eaton Adapter SAE 37 Straight provides a reliable straight-configuration connection point where SAE 37-degree flare fittings are required. Manufactured under the Aeroquip brand, this adapter is built to meet the demands of industrial hydraulic assemblies where consistent sealing and mechanical integrity are critical.

The SAE 37-degree flare design ensures a metal-to-metal seal that performs reliably under the pressure and vibration conditions typical of mobile and stationary hydraulic equipment. Straight adapters of this type are commonly used to transition between differently threaded ports or to facilitate assembly and maintenance access without altering line routing.
