I’ve kept the rubber plunger out of the tube when in storage. When kept inside the tube it compresses the rubber and retains the shape memory which causes it to fail. Haven’t ever replaced mine and it is eight years old. Still works perfectly.
My original one i had to do this but the one i have now, if you fully depress the plunger with no coffee in it it comes out the bottom just enough to not squeeze the sides.
