Thread Adapter M22x1 Male and M20x1 Male Chrome - for a Standard tap Aerator Thread

Very well-engineered adapter, but seems rather expensive. I needed an adapter to allow a swivel tap aerator to be fitted to my kitchen tap which takes a 20mm male-threaded aerator. Unfortunately, none of my local plumber's merchants (I tried 5 suppliers) could source a male-to-male 20-to-22mm thread adapter so I was lucky to find this adapter on Amazon. I initially balked at the price as it seemed rather high, but I decided to order it as it was exactly the design that I needed. But I'm pleased that I did order this adapter as it fits perfectly, it looks good, and the tap has no leaks whatsoever.I've added a photo that shows the adapter and the swivel tap aerator - the adapter adds only about 10-12mm to the overall length.
