The non-metallic expansion joint are flexible connectors designed to eliminate the thermal stress created by absorption of displacement from thermal changes in ducting systems. It also absorbs vibrations and compensates for minor installation errors in its ducting or equipment. They are fabricated from a wide variety of non-metallic materials, including synthetic elastomers, fabrics, insulation materials and fluoroplastics, depending on the designs

Benefits

• Lower material costs
• Minimal shipping and installation costs
• Vibration reduction.
• Minimal field assembly requirements.
• Superior corrosion resistance
