Randy,

No, I can't design around commonly available ones.
I've tried, but the profile I *need* to
have makes using stock ones problematic.
There's 8 outside curving bends, and 4 inside
curving bends that are necessary to move around
obstructions and stay within the sealing surface.
Plus, I've tried altering the path of the groove I insert
them into but can't get it to fit a stock size perfectly, either.
So... any leads on DIY rubber gasket/o-ring molding?


If you can use a standard round or square cross section and just need a
non-standard length, but o-ring cord stock and splice it with Loctite
404. See McMaster p.3217. Cord stock is on p.3282. Unfortunately, 404 is
expensive and has a relatively short shelf life, but it makes a
surprisingly strong joint that works fine for static seals.

Super glue also works for this. Though if exposed to water it may
fail. It sure doesn't when in an oily area.
