AEROQUIP

Description & Features

Constructed from brass and carbon steel, this -40 dash size flanged hose fitting is part of the Aeroquip 4775 Series reusable fitting line, designed to SAE Code 61 standards. The flanged end connects to the line or hose side, making it suited for larger-bore hydraulic hose assemblies where reusable fittings offer a practical advantage over crimp-only solutions.

Aeroquip reusable fittings are built to handle a wide range of industrial hydraulic applications. The design supports faster assembly times compared to permanent alternatives, and the dual-material construction, brass and carbon steel, provides reliable performance across varying system conditions. As a fitting assembly, this unit arrives ready for installation without requiring additional components to complete the connection.
