Oil Pickup & Transmission Screen in 304 Stainless Steel (AISI 304 (1.4301)) is used for protecting the engine oil pump and transmission hydraulics from large debris at the sump pickup and valve-body inlet. 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.
