Parker NV106CA-6-4 Straight Needle Valve 3/8 X 1/4 in Brass

Product Description

The PARKER NV106CA-6-4 is a straight needle valve designed for precise flow control in compressed gas and fluid systems. It features a brass body and brass needle, with a compression inlet connection on the 3/8-inch tube side and a 1/4-inch NPTF male pipe outlet. Rated to 150 psi maximum working pressure, this valve handles temperatures from -45 degrees F to 250 degrees F, making it suitable for a wide range of HVAC, refrigeration, and plumbing service applications. Overall length is 1.78 inches and overall height is 1.53 inches. Licensed HVAC technicians, plumbers, and pipefitters typically install this valve where fine flow adjustment is required at a connection point.

This valve fits inline service and instrumentation applications where a compression tube meets a threaded male pipe fitting. Common install scenarios include refrigeration line service ports, instrument isolation, and fluid control in light commercial or residential HVAC systems. The 1/4-inch NPTF thread ensures a pressure-tight seal with standard tapered pipe fittings. The compact overall dimensions make it suitable for tight-space installations in equipment cabinets and utility chases.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or pipefitter. Shut off system pressure and depressurize the line before removing or installing the valve. Use thread sealant or PTFE tape rated for the application on the NPTF male pipe threads; verify the compression fitting ferrule is properly seated before tightening. Follow applicable IPC or IFGC code requirements for the system being serviced.
