Toilet Fill Valve Inlet Filter Screen in 304 Stainless Steel (AISI 304 (1.4301)) is used for stopping sand and scale at the toilet cistern fill-valve inlet, where a single grain on the valve seat keeps the toilet running and wastes water. 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.
