CANTEX Schedule 40 Conduit is engineered with PVC to resist rust and corrosion in underground applications. The belled end design helps promote easy installation and eliminates the need for special coupling. It also helps provide a stronger joint with fewer chances of leakage and less pull-apart during installation. In addition to underground installation, Schedule 40 can be used in walls, floors, and ceilings under NEC Article 352.
