Parker® NV106C-6-4 Brass Inline Needle Valve, 3/8 in x 1/4 in, Compression x Male Pipe, 150 psi, -45 to 250 deg F

Needle valves create a means of controlling the flow of liquids or gases through the valve mechanism. It is possible to easily adjust the flow rate to any specific amount desired, making the needle valve useful in a number of applications. Parker's all brass needle valves have metal-to-metal seats with fine thread screw down making them ideal for situations in which the desired flow must be maintained with little to no variance.
