Seal Installation
The seal installation tool can be purchased from MORCOR LTD at
Sales@MORCORLTD.com part number MGT045.
To begin the procedure, all of the sealing components; Seal Rings
(metal rings); O-Rings and the housings must be clean and free of
Oil, Grease, Dirt or Dust. Always check to make sure that there are
no nicks or burrs in the housing area that could damage the Load
Ring during installation. The use of DENATURED ALCOHOL (also
known as Wood Alcohol or Shellac Thinner) and a lint free cloth is
recommended for cleaning all of these areas.
NOTE: Follow all
Material Safety Data Sheet guidelines.
After all components have been wiped clean and have dried, the O-
Rings should be placed back on the Seal Rings in their proper
position. The O-Rings must be seated completely and tightly on the
Seal Ring. Always make sure that the O-rings are not twisted or
distorted by inspecting the mold flash (seam) on the outside
diameter to see that is running “true” with the circumference.
Eliminate O-Ring twist by gently pulling a section of the O Ring (2)
rapidly away from the Seal Ring
(1) and letting it “snap” back.
Warning: Do not place the Seal Rings face down on any hard or
abrasive surface to accomplish this! Once the O-Rings are back on
the Seal Rings, quickly swab out the housing with a clean lint free
cloth generously soaked it with Denatured Alcohol. This is to
temporarily lubricate the bore. Then, with the same cloth, quickly
swab the outside (O- Ring area) of the seal half to temporarily
lubricate the O-Ring.
