Shower Hose & Inlet Filter Washer Screen in 304 Stainless Steel (AISI 304 (1.4301)) is used for catching grit and pipe scale at the shower hose or mixer inlet so the head, thermostatic cartridge and diverter stay clear. The alloy gives good general corrosion resistance in atmosphere and fresh water and is essentially non-magnetic (annealed), with a practical service limit of approx. +450 °C continuous.
