Parker VHN6-6M Hydraulic Hose Mpt Fitting 3/8 in 4500 Psi

Product Description

The PARKER VHN6-6M is a straight male pipe thread (MPT) hydraulic hose fitting designed to connect hose assemblies to threaded ports in high-pressure fluid systems. Built from steel with an NPT-threaded connection, this fitting carries a maximum working pressure of 4,500 psi, making it suitable for demanding hydraulic circuits. The straight body measures 2.13 inches in overall length with a 3/8-inch body diameter and 3/8-inch thread size. Licensed hydraulic technicians and mobile equipment mechanics are the primary installers. The Series H designation places it within a common Parker fitting family used across a wide range of industrial and mobile applications.

This fitting is rated for use on industrial hydraulic lines, mobile equipment hydraulic circuits, and water and coolant lines. The straight configuration simplifies inline connections where no offset or angle is required. At 3/8 inch, this fitting size is frequently encountered in mid-capacity hydraulic circuits on construction equipment, agricultural machinery, and industrial machinery. Its NPT thread form provides a tapered, pressure-sealing thread engagement suited to North American hydraulic and fluid-power plumbing conventions.

Key Features

• 4,500 psi maximum working pressure for high-demand hydraulic service
• Steel construction provides durability in hydraulic and coolant environments
• NPT tapered thread for reliable sealing on standard North American fittings
• Straight body shape for direct inline hose-to-port connections
• 3/8-inch hose size and thread size for consistent sizing across hose and port
• Series H fitting family for broad compatibility with Parker hydraulic hose assemblies

Compatibility

Designed for use with industrial hydraulic lines, mobile equipment hydraulic systems, and water and coolant lines as stated by the manufacturer. Suitable for applications requiring a 3/8-inch NPT straight male fitting rated to 4,500 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanic familiar with fluid-power systems. Always depressurize and bleed the hydraulic circuit fully before removing or installing any fitting. Apply an appropriate thread sealant compatible with the system fluid on NPT threads before assembly. Do not overtighten; follow standard torque practices for steel NPT fittings per the system manufacturer's guidelines and applicable fluid-power standards.
