Does this work on the Ninja model BN751? It has 7 fins. I'm not finding replacement gaskets for this model # anywhere. Thanks

I'm not sure about the model, but it is definitely works for a 7 fun blade

Does this fit a model "bl641 30"? This exact model is not listed.

These gaskets are 3/8”wide x 3 1/2” diameter and work well with my blender, model BL482a. Best to measure your blender to see if it would fit. Gaskets do stretch some.

Has anyone tried this with the Ninja SS101 (Foodi Smoothie Maker & Nutrient Extractor)?

Yes, I tried it they are perfect
