Parker 11543-12-12 Sae Code 61 Flange Head Hose Fitting

Product Description

The PARKER 11543-12-12 is a straight SAE Code 61 flange head fitting designed for use with high-pressure hydraulic hose assemblies. Machined from steel and threaded at 3/4 inch, this fitting accepts hose with a 0.75 inch inside diameter (size 12) and measures 3.54 inches overall in length. It is used to create secure, leak-resistant connections at hydraulic system ports and hose ends in mobile and industrial hydraulic circuits. Installation is typically performed by hydraulic system technicians and fluid power specialists working on equipment where SAE Code 61 flange connections are specified.

This fitting is suited for use on medium- to high-pressure hydraulic hose assemblies in industrial and mobile equipment applications. The straight body geometry makes it a direct, in-line connection option where hose routing allows a 0-degree transition at the port or hose end. It is rated for use with a broad range of Parker hose series, making it a widely applicable component for field and shop assembly work.
