The print seems to work fine, although it doesn't fit as well as the original print. I am disappointed however as I thought it would be a pack of 10 seals based on one of the four reviews there were when I ordered myself. It is not. This is only one. $7 for 10 stamps makes sense to me. $7 for a glorified o-ring is a complete rip off. You can buy a brand new tank from Hoover for around $40. Hopefully it will retain its tightness despite the poor fit, but I'm not happy with the cost and expect it to be a 10 pack.
