Oster or Sunbeam Replacement Jar nut for blender Black container bottom coupling

This jar fits Oster & Sunbeam blenders, Fits the new Blenders and older ones, deven if they are over 40 years old!  This part screws onto the bottom of the Jar.  The seal sits above on the Cutter/Blade.

Fits Oster Kitchen Center Blender too as well.  We have the cutters, jars, seals and more!

These older Blenders seem to last forever, a new cutter/blade would be a good idea!
