Parker 4050-4P Hydraulic Coupler 1/2 Inch 3000 Psi Nptf

Product Description

The PARKER 4050-4P is a poppet-style female pipe thread hydraulic coupler designed for high-pressure hydraulic fluid transfer applications. Built from steel with an NPTF threaded connection, this straight-body coupler handles working pressures up to 3,000 psi and a maximum flow rate of 12.00 GPM. It measures 2.6 inches in overall length with a 0.5 inch body diameter and a 1/2 inch thread size. Part of the Parker 4000 Series, it meets ISO 5675 standards. This coupler is installed by hydraulic technicians and equipment mechanics on mobile and stationary hydraulic systems.

This coupler is suited for add-on hydraulic circuits, hydraulic loaders, and hydraulic tools where a reliable, leak-resistant female pipe thread connection is required. The poppet valve design provides automatic shutoff when disconnected, minimizing fluid loss and contamination during line changes. It is appropriate for both light industrial and field service environments where a 1/2 inch NPTF port is present on the hydraulic circuit.

Key Features

• Poppet valve design provides automatic shutoff on disconnect to minimize fluid spill
• 3,000 psi maximum working pressure for demanding hydraulic circuits
• 12.00 GPM maximum flow rate supports high-demand hydraulic tool applications
• NPTF threaded connection provides a pressure-tight seal without sealant tape on conforming ports
• Steel construction for durability in hydraulic service environments
• ISO 5675 compliant for standardized hydraulic quick coupler interchangeability

Compatibility

Designed for use with add-on hydraulic circuits, hydraulic loaders, and hydraulic tools equipped with a 1/2 inch NPTF female pipe thread port. Part of the Parker 4000 Series hydraulic quick coupler line and rated to ISO 5675.

Installation Notes

Installation should be performed by a qualified hydraulic technician or equipment mechanic. Before servicing, fully depressurize and bleed down the hydraulic circuit to zero pressure, then shut off the power source to any hydraulic pump. Inspect the NPTF threads on both mating components for damage before assembly, and verify the port thread standard matches before applying torque. Follow applicable equipment manufacturer guidelines and applicable industry standards for hydraulic fitting assembly.
