Parker NV104C-4-4 Angled Needle Valve 1/4 in Brass

Product Description

The PARKER NV104C-4-4 is an angled needle valve designed for precise flow control in compressed air, hydraulic, and fluid system lines. It features a brass body and brass needle, with a compression inlet and male pipe outlet configuration in a 1/4 inch size. Rated to 150 psi maximum working pressure, it handles temperatures from -45 degrees F to 250 degrees F. The compact form factor — 1.38 inches overall length and 1.8 inches overall height — suits tight installation spaces. Licensed plumbers and HVAC technicians commonly install this valve for metering or shutoff service in low-to-medium pressure systems.

This valve is suited for residential and light commercial applications where a compact angled configuration is needed to redirect flow while maintaining fine throttle control. Typical installations include compressed air lines, refrigeration service ports, fuel lines, and instrumentation tubing where a 1/4 inch NPTF threaded outlet and 1/4 inch OD tube compression connection are required. Its angled body makes routing easier in panel or manifold-mounted assemblies.

Key Features

• Angled body style for easier routing in confined or panel-mount installations
• Compression inlet to 1/4 inch male NPTF pipe outlet configuration
• Brass body and brass needle for corrosion resistance in common fluid and air service
• 150 psi maximum working pressure rating
• Wide operating temperature range: -45 degrees F to 250 degrees F
• Compact size: 1.38 inches overall length, 1.8 inches overall height

Compatibility

Designed for use with 1/4 inch OD tubing on the compression end and 1/4 inch NPTF threaded ports on the male pipe end, suitable as an OEM-style or replacement needle valve in low-to-medium pressure fluid and gas control applications.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified pipefitter familiar with the applicable system type and local codes. Depressurize and isolate the system fully before removing any existing valve or fitting. Apply appropriate thread sealant to NPTF connections per the system fluid compatibility requirements. Do not exceed the rated working pressure or temperature limits of the valve.
