6 x 10 Micron Racor Filter elements
I have six 10 micron Racor Filter elements for a 500 Series Filter for sale. These are the blue filter elements, Part #2010TM-OR.
They are in their original sealed plastic wrapping, and include the gaskets.
$48 for all six - that's a very reasonable $8 each!
I'll mail them to you, if you are not in the Stuart FL area.
