n Before you begin
Tools Needed
Specific tools are required for cleaning
and tensioning the bolts. Always use
standard safety equipment and follow
good safety practices. The following
tools are required for removal of the old
gasket and installation of the new
gasket:
• Calibrated torque wrench or
hydraulic tensioner
• Brass wire brush
• Personal safety equipment
• Lubricants for the bolts (if
specified)
Clean and Examine
Clean and examine the flange
surfaces. Make sure all foreign
material and debris from the flange
surfaces, fasteners (bolts or studs),
nuts and washers are removed. Use a
brass wire brush in the direction of the
grooves to clean the flange surfaces.
Examine the flange surfaces, fasteners
(bolts or studs), nuts and washers to
ensure they are free from any serious
defects. Replace any components if
found to be defective. If in doubt, seek
advice.
n Gasket Dimensions
Ensure the gasket is the correct size.
Bolt Holes
Cut the bolt holes slightly larger than
the bolts to simplify the centralization of
the gasket.
Inner Diameter
The inner diameter of the gasket
should not be smaller than the inner
diameter of the flange.
Storage and Handling
The gasket should be stored
horizontally to avoid tensions and
warping. Ideal storage conditions are
in a clean area (ideally in a plastic bag)
at <75°F, 50 - 60% humidity, and out of
direct light.
All types of gaskets should be handled
with care. Carry gaskets carefully,
ideally in some form of protective cover.
Protect the surfaces and do not bend or
write on the gasket.
