Pfeiffer DUO 2.5
Pfeiffer DUO 2.5C
If you own either of these pumps and are doing any repair work, this is the correct gasket for the job.

Resists oil: It does not swell or crack when it touches vacuum pump oil.
Lasts longer: Viton gaskets last much longer than standard rubber gaskets.
Handles chemicals: It stands up to many harsh chemicals and gases.
