Parker NV107P-4 Straight Needle Valve 1/4 in Nptf Brass

Product Description

The PARKER NV107P-4 is a straight-pattern needle valve designed for precise flow control in fluid and gas systems. The body and needle are both brass construction, giving it solid corrosion resistance for a wide range of media. At 1.65 inches overall length and 1.54 inches overall height, it fits tight spaces without sacrificing durability. Rated to 150 psi maximum working pressure and rated for temperatures from -45 degrees F to 250 degrees F, this valve suits demanding service conditions in HVAC, refrigeration, plumbing, and industrial fluid control applications. The 1/4-inch NPTF male-to-male pipe connection makes installation straightforward for licensed tradespeople working with threaded pipe systems.

This needle valve is well suited for residential and light commercial applications where fine throttling or shutoff control is needed in a compact form. Common install scenarios include refrigerant line service ports, instrument air lines, fuel systems, and hydraulic control circuits. The straight body style keeps the flow path direct, reducing pressure drop in the line. The NPTF thread standard ensures a pressure-tight dryseal connection without relying solely on thread sealant, which is particularly useful in gas and refrigerant service where leak integrity is critical.

Key Features

• Straight-pattern body for direct, low-restriction flow path
• Brass body and brass needle for corrosion resistance across a range of fluids
• 1/4-inch NPTF male-to-male pipe connections for dryseal, leak-resistant fit
• 150 psi maximum working pressure rating
• Wide temperature range: -45 degrees F to 250 degrees F
• Compact size: 1.65 inches OAL, 1.54 inches OAH

Compatibility

Designed as an OEM-style replacement or direct-install needle valve for 1/4-inch NPTF male pipe threaded systems in HVAC, refrigeration, plumbing, and industrial fluid control applications.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified pipefitter familiar with threaded pipe systems and applicable codes. Shut off system pressure and depressurize the line completely before removing or installing any valve. Apply thread sealant or PTFE tape as appropriate for the media, noting that NPTF threads are engineered for dryseal performance. Do not exceed the rated maximum working pressure or temperature for this valve.
