Parker PP-00521 Hydraulic Hose Fitting 4mm Swivel Elbow

Product Description

The PARKER PP-00521 is a female metric L 24-degree cone swivel fitting with a 45-degree elbow configuration, designed for use in hydraulic hose assemblies. Constructed from steel, this fitting connects a 4 mm (1/4 inch) hydraulic hose to a threaded port using an M12 x 1.50 metric thread. The swivel design allows the fitting to rotate during installation, reducing hose twist and making it easier to route lines in tight or angled spaces. It is intended for professional hydraulic system installation and maintenance performed by qualified fluid power technicians or industrial mechanics.

This fitting is suited for hydraulic systems that require a 45-degree elbow connection at the hose end, commonly found in mobile equipment, industrial machinery, and power units. The 24-degree cone seat provides a leak-resistant metal-to-metal seal at the port interface. With a 4 mm hose size and M12 x 1.50 thread, it is appropriate for compact hydraulic circuits operating on light to medium equipment where precise hose routing at an angle is required.

• Swivel end rotates during installation to prevent hose twist and reduce assembly stress
• Steel construction delivers durability in demanding hydraulic service conditions
• M12 x 1.50 metric thread matches standard metric port sizes used on European and international equipment
• Compatible with 4 mm (1/4 inch) hydraulic hose assemblies

Compatibility

Designed as an OEM-style hydraulic hose fitting for systems using 4 mm hose with M12 x 1.50 metric threaded ports and a 24-degree cone seat interface.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the cone seat and port threads for damage before assembly, and tighten to the fitting manufacturer's standard torque range for the thread size using a calibrated torque wrench. Do not over-tighten or use thread sealant compounds on metal-to-metal cone seat fittings.
