Flow Regulator

thingiverse

This is a cap that fits over the end of a PVC pipe to regulate the output flow of water. The Flow outlet fits over the PVC pipe and comes in several sizes depending on the pipe it should attach to. It should fit securely, but there are also screw holes if you need to attach it more securely. The Flow Knob is secured to the Flow Outlet with either a M3 or #4 machine screw (stainless). Washers and a lock nut are recommended. Higher numbers mean larger aperture and greater flow. The picture shows it fitting over a valve, but they are not standard sizes outside, so the flow outlets are designed for various size PVC pipes. The same size flow knob works with all sizes of the flow outlet.
