Non-Metallic Conduit also comes in rigid and flexible types.
- Non-metallic conduit is typically made from PVC and is a good choice for outdoor residential applications.
- Blue electrical non-metal tubing (ENT) is for indoor use only. Some code-compliant PVC fittings can be used with ENT inside walls, floors, some ceilings or encased in concrete.
- Outdoor flexible non-metallic tubing is strong and watertight, non-corrosive and weighs less.
- Metal or plastic boxes can be used with nonmetallic conduit.
