Fabric Expansion Joints
Fabric expansion joints are flexible, corrosion-resistant connectors ideal for high-temperature gas ducts and industrial ventilation systems.
Lightweight, Multi-Layer Joints for Gas and Duct Systems
Fabric expansion joints are specially designed for low-pressure, high-temperature gas ducts where metallic joints are not feasible. Constructed from multiple layers of heat- and chemical-resistant fabrics, these joints provide flexibility, vibration absorption, and movement compensation in systems handling hot air, flue gas, or corrosive fumes.
