There is a longer version 65110976 available from a number of different suppliers (not via Amazon) which is 44.5cm or 17.5 inch. I got mine from Advanced Water Company. The shorter one via Amazon is about £14 whilst the longer one I paid £21 for but various firms charge a wide variety of prices of anything up to almost twice as much; shop around! All measurements are for the brass element itself not including the grey connecting end. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quick delivery and exactly what was needed *by M***L on 22 October 2019* Perfect.
