My old canners are not rubber safety valves they are the ball spring type and adjustable.
I bought a new gasket for the kook Kwick it is too big around but I can cut it down other than that it will work fine.
It is for an old presto.
It came with a new over pressure plug I have no use for.
You are right you have to maintain these things to be safe and rubber turns into a rock over time and is of no use.
I really think they should go back to the other ones.
I test mine every time I use it.
I usually set it at about 14 to 15 psi.
