Parker VHC4-4F Hydraulic Valve Fitting 6500 Psi 1/4 Inch Nptf

Product Description

The PARKER VHC4-4F is a straight hydraulic hose valve fitting designed for high-pressure fluid control in industrial and mobile hydraulic systems. Built from steel with a 1/4-inch NPTF threaded connection, it carries a maximum working pressure of 6,500 psi and handles temperatures from -35 degrees F to 250 degrees F. The VHC4-4F belongs to Parker Series H and is installed by hydraulic system technicians, equipment mechanics, and fluid power specialists who need a reliable, leak-resistant fitting in demanding service environments.

This fitting is suited for use in industrial hydraulic lines, mobile equipment hydraulic circuits, and water and coolant lines. Its straight body profile and threaded NPTF interface make it appropriate for direct hose-to-valve connections where a compact, inline fitting is required. The 1/4-inch hose size and 0.25-inch coupler diameter fit common small-bore hydraulic hose assemblies found in both stationary machinery and mobile equipment.

Installation Notes

Installation is performed by qualified hydraulic technicians or equipment mechanics. Depressurize and drain the hydraulic circuit completely before removing or installing any fitting. NPTF threads rely on thread interference for sealing — inspect threads carefully and avoid cross-threading. Follow applicable industry standards and equipment OEM torque guidance when tightening hydraulic fittings.
