Fabric Expansion Joints For High Temp Flue Ducts

ThermaFlex Fabric Expansion Joints are non-metallic flue duct expansion joints that provide stress relief for piping and ducting systems by absorbing thermal growth and shock, isolating mechanical vibration, and allowing for misalignments.ThermaFlex expansion joints are precision engineered specifically for your application.
ThermaFlex Flue duct expansion jointsare custom engineered to handle low pressure (±3 psig) applications with temperatures ranging from -100°F to more than 2000°F. Industry Proven materials and precise engineering go into every Thermaflex Fabric Expansion joint.
