FPLC and crumbling rubber o-rings

Hi all.
So, we have this FPLC-apparatus from Pharmacia..
Pharmacia service costs are high, so we usually service it ourselves.
Problem is the rubber o-rings in the pumps. They crumble and leave
rubber-dust that clogs up the filters. 
Tried different types of rubber - no luck - even the Pharmacia ones
crumble.

Have anyone out there found a supplier of O-rings that are able to
successfully endure both the chemical and the physical stress of being
shoved around in a glass shaft for months?

Any help appreciated greatly.
- Max
