Nice effort!  Solid rubber pistons are easy to make but at high pressures they do have their disadvantages due to the lack of rigidity.

400 psi in a plastic pen? That is not a good idea. Those pens are kind of brittle, so if one failed in your hand it would hurt a lot and also cause serious injury. Please use SCH 40 steel pipe for those pressures.

He's using brass tubing, not the actual pen.
In regards to your other post, before you bring it up, there are a lot of things not rated for pressure that we use anyway... not always the right thing to do, but we're all adults capable of making a guided decision. For instance: a lot of the higher mixture hybrids we have on the sight are made from non-pressure rated parts, or parts par past their pressure rating.
