Parker BD-1177716-16-1 Hose Fitting 45 Deg Elbow 1 in

Product Description

The PARKER BD-1177716-16-1 is a 45-degree elbow hydraulic hose fitting designed for use with high-pressure hydraulic hose assemblies in industrial and mobile equipment applications. Constructed from steel, this flanged fitting features a 1-inch hose inside diameter and an overall length of 5.07 inches (128.80 mm). It conforms to ISO 12151-3-E45M-L and is built to SAE shaft-type standards, making it a reliable choice for technicians assembling or replacing hydraulic lines in demanding environments. The size-16 designation places it in Parker Series 77 hose end fittings.

This fitting is specifically listed for use with 787TC and 797TC hose. It suits mobile hydraulic systems, construction equipment, and industrial machinery where a 45-degree elbow transition is required at the hose termination point. The flanged connection type provides a secure, leak-resistant interface under cyclic pressure conditions. Installation is typically performed by hydraulic system technicians or millwrights during hose assembly fabrication or field repair of mobile equipment hydraulic circuits.

Key Features

• 45-degree elbow geometry for routing hydraulic lines in tight or angled installations
• Steel construction for durability under high-pressure hydraulic service
• Flanged connection type for secure, leak-resistant termination
• Conforms to ISO 12151-3-E45M-L for standardized interchangeability
• SAE shaft type with size-16 hose designation (1-inch inside diameter)
• Overall length of 5.07 inches to aid assembly layout planning

Compatibility

Designed for use with Parker 787TC and 797TC hose, size 16, with a 1-inch inside diameter. Verify hose end series and pressure ratings before assembly.

Installation Notes

Hydraulic hose assembly and fitting installation should be performed by qualified hydraulic technicians. Depressurize and lock out the hydraulic system completely before disconnecting any existing lines or fittings. Use proper crimping or swaging equipment rated for the hose and fitting series — do not attempt to install hose fittings without the correct assembly tooling. Inspect the fitting and hose end for damage before assembly and verify that all thread and flange interfaces are clean and free of debris prior to connection.
