Two-Piece PVC Expansion Coupling, 3-1/2 in.
This two-piece expansion coupling is designed for 3-1/2 inch PVC conduit systems, providing up to 6 inches of expansion to compensate for thermal movement in exposed conduit runs. The PVC construction ensures compatibility with rigid PVC conduit systems.
Specifications
- Conduit Size: 3-1/2 in.
- Expansion Capacity: 6 in.
- Type: Two-Piece Expansion Coupling
- Material/Finish: PVC
Applications
Used on exposed PVC conduit systems where large-diameter conduit is subject to thermal expansion and contraction, particularly in outdoor installations, rooftop runs, and industrial environments with wide temperature variation.
