Expansion Joints

Ductwork

U.S. Bellows provides custom designed expansion joints in ductwork and fabricated ductwork assemblies. The assemblies may include fabricated elbows, tees, and straight sections of ductwork, in carbon steel or stainless steel, and in diameters of 42″ or larger. The duct sections can include fabric or metallic expansion joints and can be rectangular or round. View Product Information

Fabric Expansion Joint

A very low pressure flexible ducting element that consists of round or rectangular fabric bellows sections and accompanying end connections. Most motions allowed. View Product Information

Thick Wall Expansion Joints
