Designed for use in instrumentation, hydraulic, and pneumatic systems, the Danfoss / Eaton Brass Adapter provides a straight connection between a 1/8 in. NPTF male thread and a 3/16 in. female hose, pipe, or tube end. Constructed from brass, it is suited for applications where corrosion resistance and reliable sealing are priorities across a wide temperature range, rated down to -65°F.
Manufactured under the Eaton Aeroquip line, this adapter features Dura-Kote plating for additional corrosion protection and is engineered to perform at operating pressures above SAE standards. The 7/16 in. hex on the female end allows for straightforward installation with standard tooling. Aeroquip's broad range of adapter styles makes it practical to configure connections across varied system layouts without compromising performance.
