Parker VHN6-6F Hydraulic Hose Valve Fitting 3/8 in 4500 Psi

Product Description

The PARKER VHN6-6F is a straight hydraulic hose valve fitting rated for 4,500 psi maximum working pressure. Built from steel with an NPTF threaded connection, it is designed for use in high-pressure hydraulic plumbing on industrial and mobile equipment. The fitting measures 1.84 inches in overall length with a 3/8 inch hose size and 3/8 inch thread size. It is sized for demanding fluid-power circuits where leak-free, threaded connections are required. Licensed hydraulic technicians and fluid-power mechanics install this fitting as part of hose assembly or valve manifold work in the field or in a shop environment.

The VHN6-6F is suited for industrial hydraulic lines, mobile equipment hydraulic circuits, and water and coolant lines. Its straight geometry makes it a direct inline connector between hose ends and valve bodies where no angle offset is needed. The NPTF thread form provides a pressure-tight mechanical seal without relying solely on sealant. It fits applications operating within a temperature range of -35 degrees F to 250 degrees F, covering most standard hydraulic fluid operating conditions encountered in construction, agriculture, and industrial machinery.

Key Features

• Steel construction for durability in industrial and mobile equipment environments
• NPTF threaded connection delivers a pressure-tight mechanical seal
• Straight shape for direct inline hose-to-valve connections
• Operating temperature range of -35 degrees F to 250 degrees F
• Series H fitting — 3/8 inch hose size and 3/8 inch thread size in a compact 1.84 inch overall length

Compatibility

Designed for use with industrial hydraulic lines, mobile equipment hydraulic systems, and water and coolant lines requiring a 3/8 inch NPTF straight valve fitting at up to 4,500 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid-power mechanic. Depressurize and isolate the hydraulic circuit fully before removing or installing any fitting. NPTF threads rely on thread-form interference for sealing, but applying an appropriate thread sealant compatible with the system fluid is common practice on external threads. Inspect threads and seating surfaces for damage before assembly and torque to the fitting manufacturer specifications using a calibrated torque wrench.
