These Genuine, New Old Stock, Racor 2040SM filters were commonly referred to as ‘Racor 2040SM Brown Top’ filters. It’s easy to see why they were called brown top, at the time, Racor was producing the filters with the plastic ends of the filters with their respective colors. In this example, a “Brown Top” also represents the series “SM” which is a 2-Micron element. These 2040’s can be used in any Racor 900 Series Turbine Assembly.
The filters come packaged in factory plastic in a factory box. They are 100% genuine Racor and are perfectly functional.
