8mm Push in Needle Valve

Allows for fine control for gas and liquid flow.

A needle valve gives you fine control over gas or liquid flow, where a ball valve only gives you on or off. Turning the adjustment screw moves a tapered needle in and out of a matching seat, so you can dial in a precise flow rate rather than just opening or closing the line.

This one has an 8mm (5/16") push-in fitting on both ends, so it fits straight into an EVABarrier line or any other duotight-compatible 8mm tubing without clamps or tools.

These are commonly used in reflux condensers to adjust the reflux ratio.
