Low Flow Screw

The Low Flow Screw is responsible for controlling the rate of flow during the initial part of the pour. 

It threads into the brass High Flow Adjustment Screw and is found on all Evolution Series, WGC100/250, and WG8/10 systems. 

Each Low Flow Screw is wrapped in PTFE tape to help prevent it from unthreading or damaging the High Flow Screw's brass threads during operation.
