Parker NV102F-4 Straight Needle Valve 1/4 in Flare Brass

Product Description

The PARKER NV102F-4 is a straight needle valve designed for precise flow control in refrigeration, HVAC, and fluid-handling systems. Built with a brass body, it features flare x flare end connections on a 1/4 inch tube outside diameter and is rated for a maximum working pressure of 150 psi. The valve handles a wide service temperature range, from -45 degrees F to 250 degrees F, making it suitable for both refrigerant lines and other fluid circuits where accurate shut-off or throttling is required. HVAC technicians and refrigeration service professionals are the primary installers of this type of fitting.

This straight needle valve is well-suited for residential and light commercial HVAC and refrigeration applications where flare connections are standard. Typical installation scenarios include refrigerant line service ports, gauge manifold connections, and other low-to-medium pressure fluid circuits. The flare x flare configuration is common on copper tubing used throughout refrigerant systems, making this valve a practical inline flow-control component for service and installation work.

Key Features

• Straight inline configuration for direct installation in refrigerant or fluid lines
• Brass body construction provides corrosion resistance and durability in HVAC and refrigeration environments
• Flare x flare end connections compatible with standard 1/4 inch OD copper tubing
• 150 psi maximum working pressure rating for low-to-medium pressure service
• Wide temperature range from -45 degrees F to 250 degrees F suits diverse refrigerant and fluid applications

Compatibility

Designed as an OEM-style replacement or service valve for HVAC and refrigeration systems using standard 1/4 inch flare connections on copper tubing.

Installation Notes

Installation should be performed by a licensed HVAC technician or refrigeration mechanic. Always recover refrigerant and depressurize the system before replacing or installing any valve in a refrigerant circuit. Use proper flare nut torque practices and inspect flare seats for damage before making connections. Installations involving refrigerants must comply with applicable EPA Section 608 requirements and local mechanical codes.
