Parker VHN4-4F Hydraulic Hose Valve Fitting 1/4 in 6500 Psi

Product Description

The PARKER VHN4-4F is a straight hydraulic hose valve fitting designed for high-pressure fluid power systems. Built from steel with a 1/4 inch body diameter and NPTF threaded connection, it delivers a maximum working pressure of 6,500 psi and handles temperatures from -35 degrees F to 250 degrees F. At 1.65 inches in overall length, it provides a compact, robust connection point between hydraulic hoses and valve ports. This fitting is a Series H component intended for installation by hydraulic system technicians and fluid power mechanics working on industrial and mobile equipment applications.

The VHN4-4F suits a range of fluid handling environments. Primary applications include industrial hydraulic lines, mobile equipment hydraulic systems, and water and coolant lines. The NPTF thread form creates a pressure-tight, leak-resistant seal without relying on a separate thread sealant compound, making it well suited for high-cycle and high-vibration environments common in mobile and industrial hydraulic circuits.

Key Features

• 6,500 psi maximum working pressure for demanding hydraulic service
• NPTF threaded connection provides a dry-seal, pressure-tight fit
• Steel construction for durability in industrial and mobile equipment use
• Straight body shape simplifies inline hose-to-valve connections
• Wide temperature range: -35 degrees F to 250 degrees F
• Compact 1.65 inch overall length for tight installation spaces

Compatibility

Designed for use with industrial hydraulic lines, mobile equipment hydraulic systems, and water and coolant lines requiring a 1/4 inch NPTF threaded straight hose valve fitting rated to 6,500 psi.

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 fitting. Inspect NPTF threads for damage before assembly and apply thread engagement to the appropriate number of turns per NPTF dry-seal specifications. Torque to the fitting manufacturer and system design requirements; do not overtighten, as this can crack the fitting body or distort the thread seal.
