Parker NV101F-6-4 Angled Needle Valve Flare to Male Pipe Brass

Product Description

The PARKER NV101F-6-4 is an angled needle valve designed for precise flow control in refrigeration, HVAC, and fluid-handling systems. The valve features a brass body with a 3/8-inch tube outside diameter on the flare end and a 1/4-inch NPTF male pipe end, making it a compact fitting-to-pipe transition point. It handles a maximum working pressure of 150 psi and operates across a temperature range of -45 degrees F to 250 degrees F. HVAC technicians and plumbing professionals install this valve where controlled shutoff or metering of refrigerant or fluid flow is required in tight spaces that benefit from an angled configuration.

This needle valve suits residential and light commercial HVAC and refrigeration applications where a flare-to-male-pipe connection is needed at an angle. The angled body style allows installation in confined equipment panels, line sets, or service manifolds where a straight valve would be impractical. It is commonly used in service port assemblies, gauge manifold circuits, and refrigerant line isolation points. The 1/4-inch NPTF thread provides a pressure-tight seal with standard pipe fittings used throughout the trade.

Key Features

• Angled body style for installations in confined or offset connection points
• Brass body construction for corrosion resistance and durability in refrigerant and fluid service
• 3/8-inch flare tube connection to 1/4-inch NPTF male pipe end transition
• Rated to 150 psi maximum working pressure
• Wide temperature range: -45 degrees F to 250 degrees F
• 1/4-inch NPTF thread type for pressure-tight pipe connections

Compatibility

Designed as an OEM-style replacement or service valve for HVAC, refrigeration, and fluid-handling systems requiring a 3/8-inch flare to 1/4-inch male NPTF pipe angled needle valve.

Installation Notes

Installation is typically performed by a licensed HVAC technician or plumber. Recover any refrigerant and depressurize the system fully before removing or installing this valve. Use a calibrated torque wrench and follow the fitting manufacturer's recommended make-up procedure for flare connections to avoid under- or over-tightening. NPTF threads should be inspected for damage before assembly; thread sealant use should comply with system fluid compatibility and applicable mechanical codes.
