flammable. Use them only in a well ven
tilated area free from excessive heat,
sparks, and flame. Read and follow all
precautions printed on solvent contain
ers.
The seal is not normally reused because wear pat
terns on the finished faces cannot be realigned
during reassembly. This could result in premature
failure. If necessary to reuse an old seal in an emer
gency,
carefully
wash all metallic parts in
fresh
cleaning solvent and allow to dry thoroughly.
Handle the seal parts with extreme care to prevent
damage. Be careful not to contaminate precision
finished faces; even fingerprints on the faces can
shorten seal life. If necessary, clean the faces with a
non‐oil based solvent and a clean, lint‐free tissue.
Wipe
lightly
in a concentric pattern to avoid
scratching the faces.
Inspect the seal components for wear, scoring,
grooves, and other damage that might cause leak
age. Clean and polish the shaft sleeve, or replace it
if there are nicks or cuts on either end. If any com
ponents are worn, replace the complete seal;
never mix old and new seal parts
.
If a replacement seal is being used, remove it from
the container and inspect the precision finished
faces to ensure that they are free of any foreign
matter.
To ease installation of the seal, lubricate the O‐ring
and shaft sleeve with water or a very
small
amount
of oil, and apply a drop of light lubricating oil on the
finished faces. Assemble the seal as follows, (see
Figure 3).
