Rubber Flue Duct Expansion Joints are designed to handle hot air or gases in industrial duct work, as well as those generated by power plant and pollution control equipment. Options include PTFE-lined, concentric reducing, eccentric reducing, filled arch, lightweight, and off-set configurations.

Metal Expansion Joints are produced from fully annealed type 321 stainless steel sheet stock rolled into a tube and seam welded. The latest technology in forming the corrugations of our bellows is employed.

Fabric Expansion Joints are non-metallic flue duct expansion joints that provide stress relief for piping and ducting systems. These Fabric Expansion Joints absorb thermal growth & shock, isolate mechanical vibration and allowing for misalignment.

Solid-molded PTFE expansion joints are corrosion-resistant and made to withstand the high pressure and temperature in a compact, space-saving design.  Standard sizes from 1” to 12” with two, three, or five convolutions; available in sizes up to 48”.
