A conduit coupling is a PVC fitting designed to join two sections of conduit, creating a seamless and secure connection. It features smooth sockets on both ends to accommodate the conduits, allowing for a snug and stable fit. This fitting is commonly used in both rigid and flexible conduit systems, providing a dependable solution for extending conduit runs or repairing sections. Conduit couplings are essential for maintaining continuity in electrical systems, ensuring proper alignment and protection of wiring. In contrast, other fittings like male or female adapters facilitate transitions to threaded components, while couplings are exclusively used for connecting conduit sections directly.
