at the factory. Substitution of factory-supplied lubricant will
affect seal integrity. Lubrication prevents thread galling and
minimizes friction between mating metallic components
to maximize sealing gland performance when a catalog-
specified torque is applied. Lubrication should be used any
time a sealing gland assembly is opened for replacement or
adjustment of the probe(s), wires or sealant. By re-lubricating
the gland body threads and load bearing surface of the cap,
proper load transfer (sealant compression) can be achieved. Figure 2
