Three-part design
A faucet aerator with housing consists of three parts: housing, insert, and washer.
Neoperl offers inserts in five different sizes. Plus there is a Shorty model for the standard size, with a short insert that requires a shortened housing.
There is the right housing size for every insert size. You will find the matching Neoperl components in the overview below.
Housings have either a female or male thread for screwing them on the faucet spout. They are available in metric and sometimes US thread sizes.
