Aeroflow oil system filter screen fittings have a built-in oil screen filter within the aluminium fitting. This filter screen is designed to stop metal chips and debrisfrom reaching external or dry sump oil systems. The filter screen itself is made from 304stainless steel. It uses .015" diameter 16 mesh wire which is course enough toallow thick engine oil throughwith minimal restriction. Aeroflow's recommend to remove this fitting and inspect/clean out the screen every oil change.

Please Note the internal screen filter element cannot be removed from fitting itself. It is machined into the fitting so it does not fall out.
