When I say 1 time use I mean, the product will be a single use product but we will be running production, 5-10k/yr.
I also meant o-ring in reference to gasket.

A couple things to address this is 1 time use and will be filled with < 1ml of dyed liquid. Adding a gasket would help however (from my limited experience) they are expensive for the size and to assemble.
A ball bearing does not work in our application...
I'm looking for some help with a product I'm designing.
It's a marking device that has a valve at the tip. It is filled with alcohol based liquid and when the tip (see green below) is pressed the liquid flows.
Pretty much I'm reverse engineering a whiteout pen. I want to learn more about this...
