Thanks for bringing your question to Tundra Restaurant Supply.
No, this Waring 027179 Rubber Foot will not fit your BB180 NuBlend blender. Here is a parts list for your NuBlend: http://www.etundra.com/ShowDocument.aspx?fileId=330898
I believe you'll need Waring part #026278 (suction cup feet) as the correct replacement part. I've included this foot below for your convenience.
