GreyFlow™ | Feeder Pipe - Flow Restrictor

Additional flow restrictor for use on downhill runs where the slope (gradient) exceeds 3°.

Note: you will need 1 less flow restrictor in total than your total amount of runs, as the last run is non-restricted.

• 2 x 25mm Clips
• 1 x In-line Brass Sprung Check-Valve
