Over 30 years ago, I bought an old, used pressure cooker from a swap meet. Over time, the seal just wouldn't seal. I looked up the part and found it from this site. It was a perfect fit! It also came with a plug, so I replaced that as well. When I ordered it, I received an email of purchase, then another that it was mailed. Within 3 days, I had everything I needed to cook again! My neighbor was the most excited because I could cook him some beans again! It fits perfectly!
