Parker PP-00478 Hydraulic Hose Fitting 45 Degree Elbow

Product Description

The PARKER PP-00478 is a 45-degree elbow hydraulic hose fitting designed to connect flexible hydraulic hose lines at an angle, reducing stress on hose ends and improving routing in tight or congested plumbing layouts. Constructed from steel, this female-thread elbow accepts a 5/8 inch hose diameter and is built to withstand the pressure and vibration demands typical of hydraulic systems. It is a single-unit fitting suited for use during new installations or as a direct replacement in existing hydraulic circuits requiring an angled connection point.

This fitting is used in hydraulic plumbing applications across industrial, mobile, and agricultural equipment where straight connections are impractical. The 45-degree angle helps manage hose routing around obstructions, reduces bend-radius violations, and minimizes wear at the hose end. Technicians working on hydraulic power units, construction equipment, and similar machinery will find this fitting useful when re-routing or repairing hose assemblies that require an offset exit angle.

Key Features

• 45-degree elbow configuration for angled hose routing
• Steel construction for durability in high-pressure hydraulic environments
• Female shaft type for standard hose-end connection
• Compatible with 5/8 inch (10 mm) hydraulic hose diameter
• Single-piece fitting sold individually

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic hose assemblies using a 5/8 inch hose diameter with a 45-degree elbow connection requirement.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit fully before disconnecting any fittings or hose ends. Inspect mating threads and seating surfaces for damage before assembly. Torque fittings according to the hose and fitting manufacturer specifications for the applicable thread type and system pressure rating.
