This grey electrical tube of impact-resistant PVC to which polyethylene has been added (also called hostalit) has a green or red coating on the inside, which makes it easier to pull the installation wires. This electrical pipe is mainly used in places where the installation is in sight and is susceptible to damage, outdoors or underground when you want to lay a cable from the house to the shed. This grey electrical tube is more resistant to UV light and will therefore become brittle less quickly. The tube can be bent into the desired position with a bending spring or you can design the installation the way you want with the corresponding bends, connectors and clamps.
