Ask A Question

Description & Features

Designed for demanding hydraulic hose assembly applications, the Aeroquip Fitting (Perm) DKOS R2 is a -20 dash size crimp fitting constructed from carbon steel with Dura-Kote plating for reliable corrosion resistance in harsh service environments. The female swivel metric end (DKO-S configuration) accommodates line and hose connections, making it well-suited for high-duty hydraulic systems where secure, leak-resistant terminations are critical.

As part of Aeroquip's 1A Series permanent crimp fitting line, this fitting is engineered to work within a system-matched assembly approach that supports extended hose assembly service life and consistent performance under pressure. The Dura-Kote finish provides a meaningful step up in corrosion protection compared to standard zinc plating, particularly in mobile or industrial environments with exposure to moisture or chemicals.
