O-rings, of different diameters, *connected* by 3 radials, all as ONE

I'd think a decent machinist could make an aluminum mold for $150 or so,
if you can find some liquid O-ring goo to pour in there. A couple of
flat plates, a ball end mill, an entry level CNC, and you're done. Hell,
you don't even need the CNC if you know how to use a rotary table, but
it takes longer.

MIght need to spend a little time with an X-acto knife to trim the
flashing.


Gee, Smitty, if you can glue the ends of the gasket material together
o make an "O" ring, you can also glue the radials in place. At least, I
would do it for something of mine that I needed really bad. The seals
were bad on the whole house water filter when I moved into this house,
but the plastic threads on the cartridge housing were so badly worn that
the entire system was scrapped. It wasn't worth rebuilding a 20 year
old system that used VERY hard to find filter cartridges when you knew
that the hairline cracks in the clear molded plastic cartridge cover
would spread into full blown cracks and leak some day soon. I could
have even made a new cover out of some clear 4" plastic pipe I had on
hand, but why piece together a piece of worn out junk?
