Ctube Schedule 40 PVC Rigid Conduit Couplings With Center Stop

In current projects, we need a product that is lightweight, easy to bend, and resistant to corrosion. It can help us install and wire in more complex landscapes such as corners. It is the origin of ENT flexible electrical conduit.

We need higher-grade raw materials, better design, and production processes than a normal flexible conduit. To meet the relevant requirements of UL 1653, we have upgraded raw materials, processes, and formulations. At present, our quality has fully met or exceeded the relevant requirements of UL.

At the same time, to adapt to harsh environments such as being directly buried in concrete, we have fully considered every detail of the product to ensure that the corrugated pipe will not have problems in actual use (such as a wall or floor installation).

In a word, ENT flexible electrical conduit is lightweight, high strength, can be directly buried, and easily and completely adapted to different environments, saving many labor costs for your project. So it is widely used in home decoration, hospitals, government projects, etc.
