4 IN PVC EXP/DEFL COUPLING – Expansion and Deflection Coupling

The 4 IN PVC EXP/DEFL COUPLING by Thomas & Betts is a non-metallic expansion and deflection coupling designed to join two rigid PVC conduit runs where movement at structural joints is required. It is commonly used in infrastructure applications such as bridges, tunnels, inter-building walkways, docks, piers, and wastewater and water treatment facilities. This coupling provides flexible connections that accommodate axial, parallel, and angular deflections, ensuring safety and compliance with electrical codes. Ideal for electrical distributors, lighting solutions, wire and cable installations, and as a component from a switchgear supplier, it supports durable and corrosion-resistant conduit systems in demanding environments.
