GENERAL INFORMATION
Mechanical seals are precision compo-
nents that are designed exclusively for
sealing rotating shafts. This is achieved
by the contact of the two highly pol-
ished and very flat faces of the mechan-
ical seal and seat contacting. Handle
these components with care ensuring
that they are clean. Lint free gloves are
recommended for handling the seal.

adapter from the back side with a
wooden dowel.
