Geoffrey,

If you can find it that would be great. What kind of pump are you using to get the vacuum pressure with?

What do you want them for?

Could you not use a length of o-ring material?
You can buy kits for making o-rings, which are essentially a length of round rubber in rubber/viton/whatever spec, and some glue/bonding/vulcanising stuff.
I'm sure you can probably get lengths of square material aswell, which would be far better than oil soaked seals.

I bought a set of o-rings but because they are round and the rubbers fairley hard you dont get enough surface area for the vaccum, it tends to role across the rubber, my larger rubber ring is flat and compresses under the force, the o-rings dont :(

Oil filter seals aren't any softer than o-rings, and by the time they get changed, they've usually hardened up even more.

You do get o-rings made from softer material, but they're not common place.
I wonder what the proper name for the seal strip type stuff that comes in strips and used for sealing junction box covers is called. I've worked on various junction boxes, where the seal is just a press fit into a machined groove. It's usually a round or rectangular shape, and is normally very soft so you get a good seal with minimal pressure.
