304 Stainless Steel Windshield Washer Pump Strainer

A small cylindrical stainless mesh strainer on the inlet of a black windshield washer pump

Windshield Washer Pump Strainer in 304 Stainless Steel (AISI 304 (1.4301)) is used for keeping leaves, sediment and broken ice out of windshield washer pumps so the jets and pump impeller stay clear. 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.
