EN FVFA Series
Bolt Lubrication
Enardo™ provides low friction polymer coatings on carbon steel
element assembly fasteners. No additional lubrication should be
required. When stainless steel fasteners are provided, lubrication
is recommended to reduce tightening torque and to prevent
potential galling.
Lubrication will affect required torque of clean fasteners in good
condition more than any other factor. In fact, 90% of applied torque
goes to overcome friction while only 10% actually stretches the bolt.
Table 5 assumes that only machine oil is used as a lubricant. Table 6
lists several common lubricants and their effect on torque required to
stretch bolts to 50% of their yield strength. Most are available from
local bearing distributors.

Recommended Spare Parts
For installations that require frequent maintenance and minimum
downtime it is recommended that the user purchase a spare
element assembly and several spare element gaskets. The spare
element assembly can be installed immediately and the dirty
assembly can then be cleaned and be stored as a spare for the next
maintenance interval.
Element gaskets should be replaced each time the
cell assembly is loosened and removed to insure a
gas tight seal.
