Parker NV106CA-4-2 Straight Needle Valve 1/4x1/8 Brass

Product Description

The PARKER NV106CA-4-2 is a straight-pattern needle valve designed for precise flow control in small-diameter fluid and gas lines. It features a compression-to-male pipe end configuration, connecting a 1/4-inch OD tube on the compression side to a 1/8-inch NPTF male pipe thread on the outlet side. The brass body handles pressures up to 150 psi and operates across a temperature range of -45 degrees F to 250 degrees F. This valve is sized for tight installation spaces and is commonly installed by plumbers, HVAC technicians, and refrigeration mechanics where fine throttling or shutoff control is required on small instrument or service lines.

This needle valve suits residential and light commercial applications involving instrument tubing, gauge isolation, refrigeration service ports, pneumatic controls, and similar small-bore piping systems. The compression fitting on the tube side allows connection to 1/4-inch OD tubing without soldering, while the 1/8-inch NPTF male pipe thread mates directly to female pipe fittings or valve bodies. It is appropriate for use in air, water, oil, and compatible gas service within its rated pressure and temperature limits.

Key Features

• Straight-pattern body keeps the flow path in line for straightforward inline installation
• Compression-to-male pipe end connection eliminates the need for soldering on the tube side
• Brass body provides corrosion resistance suitable for water, air, and light oil service
• Rated to 150 psi maximum working pressure
• Wide operating temperature range of -45 degrees F to 250 degrees F
• 1/8-inch NPTF thread ensures a dry, pressure-tight seal with compatible female pipe fittings

Compatibility

Designed as an OEM-style replacement or new-installation needle valve for small-bore compression and male pipe applications using 1/4-inch OD tubing and 1/8-inch NPTF female pipe connections within the rated pressure and temperature limits.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or pipefitter. Shut off and depressurize the system completely before removing or installing any valve. Compression fittings require proper tube preparation — cut tubing square and deburr before seating the ferrule. Apply thread sealant compatible with the service fluid to the NPTF male threads per applicable plumbing or mechanical code requirements.
