I searched in vain for a stainless steel version. Had to settle for this brass version, but 18mm fits and woks well.

The 18mil Aerator are a good product unfortunately i bought the wrong size.

Ottimo prodotto

There is nothing wrong with the item, it just didn't fit. Must be i got odd size taps.

Ottimo prodotto, finalmente ho trovato la misura che mi serviva, quasi introvabile, l'ho cercato per mesi e finalmente ho risolto il mio problema. Grazie. Consiglio l'oggetto, la qualità è buona e funziona bene. Spero di essere stato utile

Un aireador muy bien acabado y con un precio adecuado

These 18mm Tap Aerators were bought replace the non-aerator type spouts on a hand basin in a bathroom. They appear to be of good quality and weight and were easy to fit.The resulting flow on the cold water tap was reduced and filled with bubbles created by the aerator. We no longer have to worry about the water slashing out of the sink and onto the floor or your feet, plus you are saving in your water usage. The only slight problem is the flow on the hot tap was slowed too much, this is purely down to the fact that our hot water cylinder is down stairs and so the water pressure is lower. That being said, the aerator part of the fitting is removable and so we were still able to have a matching pair of taps. I shall see if I can find another insert with a higher flow per minute, but otherwise I'm more than happy with my purchase. Just make sure you double check on the size and measure the outside edge of the screw thread (on male fitting) to ensure the correct size/fitting.
