PTFE or Silicone Based Lubricants Destroy Seals.

During installation, chances are the installation
lubricant will come in contact with sealing faces.
Once a PTFE or silicone based product touches the seal faces,
it is nearly impossible  to remove.
When the pump is started, the PTFE or silicone draws the
carbon from the primary ring, and smears this material on the
face of the mating ring, causing a build-up which eventually destroys the seal.
