- Thread-topic: nearly offtopic - grommet terminology
Maybe my google-fu has gotten weak but I thought I'd ask you lot before
having a tantrum and giving up (that's plan B). There are plenty of
practically minded DIY-ers with considerably more experience here so
hopefully someone can point out the magic term I need?
For background I'm - reluctantly - doing some case modifications for
additional cooling on a Linux box getting racked up in a dusty workshop
environment and I need easily removable dust filters mounted in
arbitrary holes punched through the case plastics.
I'd perhaps unwisely convinced myself that there must exist easily
sourced rubber double-sided grommets that would fit snugly into the
circular 80mm/120mm holes I'm going to cut. As it happens, those do
exist but seem to only be 'closed' (and are typically called "bungs"
apparently) or 'open' (such as are typically used to route wiring
through). So far so good.
What I'm having trouble finding is an open-type grommet that has, umm,
'lips' (?) on both the outwards facing rim of the grommet _and_ the
inwards facing surface so it can mate securely both to the round hole
it's going to be fitted into and then let me neatly drop in a dust
filter inside that. So the cross section of the grommet would be a H
shape basically.
Make sense? Now I can find H cross-section rubber strips that I could
cut to fit and make squared off holes instead I guess but I really
struggle to believe that these things can't be easily bought if I just
knew what they were actually called. Surely they must be really common
but perhaps in plumbing or the air conditioning industry? I've even been
combing through Ebay listings for vacuum cleaner parts...
If anyone can clue me in I'd be very grateful!
