Parker NV106C-6-4 Straight Needle Valve 3/8 X 1/4 in

Product Description

The PARKER NV106C-6-4 is a straight needle valve designed for precise flow control in compressed air, gas, and fluid systems. The brass body and brass needle construction provide reliable corrosion resistance in a compact package measuring 1.75 inches overall length and 1.56 inches overall height. It handles a maximum working pressure of 150 psi and operates across a wide temperature range of -45 degrees F to 250 degrees F. The compression-to-male-pipe end connection simplifies installation on tubing and threaded pipe runs. This valve is typically installed by licensed plumbers, HVAC technicians, and industrial pipe fitters working with low-to-medium pressure fluid or gas lines.

This valve fits applications where a compact, straight-body needle valve is needed for throttling or shut-off duty. The 3/8-inch tube outside diameter compression inlet pairs with a 1/4-inch NPTF male pipe outlet, making it a practical fit for instrument tubing connections, refrigeration service ports, pneumatic control lines, and similar light-duty plumbing or HVAC applications where space is limited and precise flow adjustment is required.

Compatibility

Designed as an OEM-style replacement or new-installation needle valve for plumbing, HVAC, and light industrial systems requiring a 3/8-inch compression inlet and 1/4-inch NPTF male pipe outlet connection.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off and depressurize the system completely before removing or installing any valve. Ensure the compression fitting ferrule is properly seated on the tubing before tightening the compression nut, and verify NPTF threads are clean and free of damage before make-up. Follow applicable IPC and IFGC code requirements for the fluid or gas service involved.
