Installation Process

1. Measure conduit run and calculate required expansion allowance for temperature variations and structural movement
2. Cut rigid conduit ends square and remove burrs to ensure proper coupling engagement and wire protection
3. Insert first conduit end into coupling, ensuring full engagement while allowing for expansion positioning
4. Position coupling at calculated expansion point, typically at building expansion joints or long straight runs
5. Insert second conduit end, setting initial gap according to temperature conditions and expected movement
6. Verify secure connection and test expansion movement to confirm proper installation and functionality

PVC Construction Advantage

Carlon PVC expansion couplings offer superior corrosion resistance compared to metallic alternatives, eliminating rust and oxidation concerns in moisture-prone environments. The lightweight PVC construction reduces installation labor while providing excellent chemical resistance and long-term durability. The non-conductive properties enhance electrical safety by preventing stray currents and maintaining proper grounding system integrity throughout the expansion range.
