Parker VHC8-8F Hydraulic Valve Fitting 4000 Psi 1/2 in Nptf

Product Description

The PARKER VHC8-8F is a straight hydraulic hose valve fitting designed for high-pressure fluid connections in industrial and mobile hydraulic systems. Built from steel with a 1/2-inch NPTF threaded connection, it carries a maximum working pressure of 4,000 psi and handles temperatures from -35 degrees F to 250 degrees F. The straight body profile and threaded shaft type make it a direct-install component for secure, leak-resistant line terminations. Licensed hydraulic technicians and mobile equipment mechanics rely on this fitting for its consistent dimensional tolerances and reliable sealing under dynamic load conditions.

The VHC8-8F is rated for use on industrial hydraulic lines, mobile equipment hydraulic circuits, and water and coolant lines. At 2.09 inches in overall length with a 1/2-inch body diameter and 0.5-inch coupler size, it fits cleanly into tight plumbing layouts on both stationary industrial machinery and field-service mobile units. Its Series H designation places it within a well-established Parker fitting family used across a broad range of hydraulic hose assemblies.

Key Features

• 4,000 psi maximum working pressure for high-demand hydraulic service
• Steel construction for durability in industrial and mobile equipment environments
• NPTF threaded connection provides a pressure-tight, dryseal fit without sealant tape in many applications
• Straight body shape simplifies inline hose-to-valve connections
• Operating temperature range of -35 degrees F to 250 degrees F suits most hydraulic fluid types
• 2.09-inch overall length keeps plumbing compact in confined equipment bays

Compatibility

Suitable for use with industrial hydraulic lines, mobile equipment hydraulic systems, and water and coolant lines requiring a 1/2-inch NPTF threaded hose valve fitting at up to 4,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanic familiar with high-pressure fluid systems. Depressurize and bleed the hydraulic circuit completely before removing or installing any fittings. NPTF threads are designed to seal on the thread form itself, but always inspect threads for damage before assembly and follow the fitting manufacturer's torque guidelines for the specific connection. Verify that all hose and fitting materials are compatible with the hydraulic fluid in the system before placing the line back into service.
