Parker H4-63 Hydraulic Hose Fitting 4000 Psi 1/2 in Nptf

Product Description

The PARKER H4-63 is a straight female pipe rigid fitting designed for hydraulic hose assemblies in high-pressure fluid and gas systems. Machined from steel with NPTF threaded connections, this fitting delivers a maximum working pressure of 4,000 psi and supports flow rates up to 12.00 GPM (45.00 LPM). The straight body geometry and 1/2 inch hose size make it a direct, rigid connection point between hose ends and system ports. Weighing 0.24 pounds with an overall length of 1.94 inches, it is compact enough for tight routing in mobile equipment and industrial plumbing installations. Licensed hydraulic technicians and industrial mechanics are the primary installers.

The H4-63 is suited for a broad range of fluid power and process applications including industrial hydraulic lines, mobile equipment hydraulics, food and chemical processing lines, water and coolant circuits, and compressed gas service. The 1/2 inch body diameter and NPTF thread type are standard sizes encountered across these industries, making this fitting a common selection for both new builds and field repairs requiring a rigid, leak-resistant hose termination.

Key Features

• Maximum working pressure of 4,000 psi for demanding hydraulic and industrial service
• NPTF dry-seal thread form minimizes risk of fluid leak at the connection point
• Straight rigid body provides a direct, non-swivel hose-to-port connection
• Steel construction suited for hydraulic fluid, coolant, water, and compatible chemical service
• Rated flow up to 12.00 GPM to support typical 1/2 inch hydraulic circuit demands
• Meets ISO 7241-1 Series B standards for hydraulic coupling compatibility

Compatibility

Designed for use with food and chemical processing lines, compressed gas systems, industrial hydraulic lines, mobile equipment, and water and coolant lines requiring a 1/2 inch NPTF female pipe rigid fitting at 4,000 psi working pressure.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial mechanic familiar with high-pressure fluid systems. Depressurize and bleed down the hydraulic circuit completely before removing or installing any fitting. Apply appropriate thread sealant compatible with the system fluid to the NPTF threads and tighten to the fitting manufacturer and system designer specifications. Inspect the connection for leaks before returning the system to full operating pressure.
