The aerator and regulator comes with a 22mm adaptor to ensure it will fit BOTH 24mm Male / outside thread and Female / inside thread taps.
24mm is the standard width, but we also offer a Male / outside thread 20mm aerator and 18mm and a Female / inside thread 19mm and 16mm tap aerator for smaller tap spouts.
If your taps do NOT have a round spout (square or oval) then our aerators and regulators will NOT fit. Be aware that some square taps still have round aerators fitted!
Please get in touch if you’ve any problems fitting our products.
