Parker KP73591 Hydraulic Hose Fitting 45 Degree Elbow

Product Description

The PARKER KP73591 is a 45-degree elbow hydraulic hose fitting designed for use in hydraulic fluid power systems where directional routing of hose assemblies is required. Machined from steel, this fitting uses an O-Ring Boss (ORB) sealing interface, which provides a reliable, leak-resistant connection under pressure. It accepts a 1-inch hose diameter and threads onto a 1-5/16-12 port. Hydraulic technicians and fluid power mechanics install this type of fitting when straight-run connections are not practical and a controlled bend angle is needed to reduce hose stress and avoid interference with adjacent components.

This fitting is suited for mobile equipment, industrial hydraulic systems, and heavy-duty machinery where 45-degree elbow transitions are needed in tight routing environments. The ORB thread form is commonly found on hydraulic cylinders, pumps, valves, and manifolds in both open- and closed-circuit hydraulic circuits. The 1-5/16-12 thread size corresponds to a larger-bore port, making this fitting appropriate for higher-flow hydraulic lines. Each package contains two fittings.

Key Features

• 45-degree elbow geometry for controlled hose routing and reduced hose stress at connection points
• O-Ring Boss (ORB) sealing interface for leak-resistant performance in pressurized hydraulic systems
• Steel construction for durability in demanding hydraulic service environments
• 1-5/16-12 thread size suitable for larger-bore hydraulic ports
• Accepts 1-inch hose diameter
• Sold in a package of 2 fittings per order

Compatibility

Designed as an OEM-style hydraulic hose fitting for use with 1-inch hydraulic hose assemblies terminating at 1-5/16-12 ORB ports on hydraulic pumps, cylinders, valves, and manifolds.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the O-ring seat and mating port for nicks or contamination before assembly, and always use a fresh, properly sized O-ring lubricated with clean system fluid. Consult the equipment manufacturer and applicable hydraulic system standards for torque and assembly procedures.
