Gas Regulator & Valve Inlet Filter Screen in 304 Stainless Steel (AISI 304 (1.4301)) is used for catching pipe scale, sealing tape fragments and debris at the inlet of gas regulators, safety shut-off valves and burner controls. 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.
