Vitamix Vita-Mix 000836 Heavy Retainer Nut with O-Ring

Is it this one? https://www.amazon.com/Vita-Mix-000836-Heavy-Retainer-Ring/dp/B00MAOGEMC?th=1 Or maybe this one? https://www.amazon.com/Vitamix-Retainer-Eastman-Tritan-Container/dp/B0028Y4CUK/ Regardless, I would not jump straight to buying a new container (likely $150+) without researching this some more. Reach out to Vitamix, maybe they can give you the part #. Or they might be even-more helpful, they have a reputation for excellent customer service. Is the machine still under-warranty? The sticker on the back (or possibly bottom) should give the manufacture date. I don't know when they started selling these, but they have a 7-year warranty: https://www.vitamix.com/us/en_us/products/7500 And honestly, although that looks rather gnarly, if it's holding and not actually leaking, you might be able to seal it up (covering the broken-plastic area) with JB Weld, and be perfectly fine, for ~$5. This area is obviously not food-contact. If it's not covered under warranty, of course. Congrats on the great score!
