304 Stainless Steel Brake & Power Steering Reservoir Strainer

A small stainless steel mesh basket strainer in the fill neck of a translucent brake fluid reservoir, engine bay, close-up

Brake & Power Steering Reservoir Strainer in 304 Stainless Steel (AISI 304 (1.4301)) is used for straining brake fluid and power-steering fluid at the reservoir fill neck so debris from containers or funnels never reaches master cylinders and pumps. 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.
