The plunger head normally:
The only differences here are that I have a slightly wider Nylon spacer since there was no exact sizing in the thread, but whatever. That shouldn't affect anything negatively on the seal.
After pulling it into the plunger tube (from the back, like you would prime it, not pushing it in)
Yeah, what the hell. Obviously it just slides over, but this is a big problem, since half the time it creates a much larger cup on one side than the other, causing me to have a shitty seal, or none at all. I thought it was just that I didn't have the wing nut tight enough, so I tightened that a little bit more, but that didn't help. Then I thought it may just be the larger washer just sliding around a little bit on the steel washer underneath, so I added a second 1 1/4" washer under that to make a "sandwich". This off-centering happens even when pulling it into the tube I make sure it's even on all sides, and I'm not sure why. It may be a slight pull from one side more than the other, but that's going to happen at least a little bit in a war situation, so this concerns me.
Any thoughts / remedies to this situation?
