Locking ring to apply on the intermediate container (for carbon and resins).
DELIVERY COULD REQUIRED UNTIL 15 WORKING DAYS
Locking ring to apply, as alternative to the closing cap, on the Smart Filters who have only one or more intermediate container (there are not final containers).
The intermediate containers are made to use light materials like carbon, which they move with the water flow, so it's necessary to put a stopper.
It's made of non toxic black PVC worked with high precision CNC machine.
