Cantex PVC Conduit Plug, Schedule 40 Fitting

Cantex 5315260 3" PVC Plug Fitting

The Cantex 5315260 is a 3" PVC plug fitting engineered to cap and seal unused conduit openings in electrical raceway systems. Manufactured from rigid PVC, this plug fitting is designed to provide a dependable, corrosion-resistant seal wherever an open conduit run, coupling, or fitting needs to be closed off. As part of the broader Cantex PVC conduit fitting line, the 5315260 plug is sized for direct use with 3" Schedule 40 and Schedule 80 PVC conduit systems, making it a practical solution for electricians and contractors who need to terminate or temporarily seal conduit runs during rough-in, renovation, or system modification work. PVC construction means this plug fitting resists moisture, corrosion, and chemical exposure far better than metallic alternatives, which is why PVC conduit accessories like this one are a mainstay in underground, wet-location, and corrosive-environment installations. The 5315260 plug is a simple but essential component — every conduit system eventually has a stub, spare, or abandoned run that needs a clean, code-conscious termination, and a properly sized PVC plug is the straightforward way to close that opening without introducing a weak point into the system. Because it shares the same PVC composition as the conduit and fittings it pairs with, the 5315260 plug can be solvent-welded in place for a permanent, watertight seal consistent with standard PVC conduit assembly practices.
