I have two Parker Hannefin filters that I found in boxes, whilst cleaning out my garage. The part number is:

CCV55248-06. These fit Racor CCV crankvent assemblies, but I don't know which one. I have not owned a boat with CCVs that I can recall, don't know how I got them.

Free to someone who will use them, themselves. You pay shipping etc. I am in Annapolis, MD
