Garlock offers a wide range of fue duct type
expansion joints for lightweight applications, especially
for scrubbers, precipitators, baghouses, and fans in air
handling systems. Style 8400 fue ducts are available
in round, rectangular or square confgurations, as belt
type (without fanges) or U-type (fanged), with virtually

ducts that require splicing into position due to obstruc-
tions or interferences that prevent continuous construc-
tion installations.
