Hydraulic reservoir non-filter: what don't I understand?

I finally removed and disassembled the hydraulic
reservoir yesterday to prepare for installing a
new pump and flushing the system, and I just don't
get why the filter/screen is made how it is.
The screen is incredibly fine mesh, which seems
wise, but the plastic housing it is welded/melted
into has two vertical slots about a mm wide that
will easily allow grit and debris through! What
don't I understand here? Looks to me like the
slots defeat the purpose of the screen!
At the bottom of the filter I found only one piece of
debris: a piece of the reservoir cap's rubber gasket,
from the outer edge, about the size of a fingernail
clipping. That's the good news. The bad news is
what I didn't find: the other piece(s) that would be
necessary to make up how much rubber was missing from
the edge of the gasket, about twice again what I did
So now I get to wonder if the missing pieces got by
the filter and helped ruin the pump, and what will
prevent such from happening again.
That gasket (assumedly inexpensive), does not show as
a separate part in ETKA, but is part of the cap assy.
($38.00); oh what a feeling! ' time to see what punch
sizes are had at local sheet metal shops.
