Flow Regulators and Service Tools
Hold the flow rate constant, then carry the key that opens the aerator.
A flow regulator maintains a predefined constant flow rate independent of the line pressure in front of it, compensating automatically for pressure variations between 1 and 8 bar. That is the difference between a regulator and a plain restrictor: one holds a number, the other just narrows the hole. This category carries both, plus the shower regulators that fit between the outlet and the hose, and the ABS service keys that remove hidden and vandal-resistant aerators without damaging the spout.
1
Regulator or restrictor
The regulator compensates across 1 to 8 bar and holds its rate. The ABS and PP restrictor is offered in two fixed options: 6 L/min in black and 9 L/min in the original colour.
2
Shower regulators fit in line
The F1/2 9L regulator and the F1/2" by M1/2" version go between the shower outlet and the hose, so the saving is added without changing the head, the hose or the mount.
3
Keys sized to the aerators
The service keys cover M22x1 or regular female, M24x1 or regular male with side flats, and M28x1 aerator threads — the same sizes the hidden and vandal-resistant aerators on this site are built in.
If you are retrofitting a building, order the regulators and the matching service keys together. A hidden aerator without its key is a maintenance problem waiting to happen.

Questions we are asked about flow regulators and service tools
What pressure range does the regulator cover?
It compensates automatically for pressure variations between 1 and 8 bar, holding the predefined rate across that band.
Which key fits our aerators?
The service key covers M22x1 or regular female, M24x1 or regular male with side flats, and M28x1. The kitchen mixer kit covers F22*1, M22*1 and M28*1.
Can a regulator be fitted to any shower?
The two shower regulators here are specified F1/2 and F1/2" by M1/2". Confirm the thread at your outlet before ordering.

How a Faucet Aerator Works
The part that decides how much water leaves a tap costs less than the washer behind it.
Read the guide →Aerator Thread Sizes Explained
Every aerator conversation ends up at the same question, and it is better to ask it first.
Read the guide →Flow Regulator or Restrictor?
Both reduce flow. Only one of them holds a number you can put in a specification.
