The protective tube is used to install the temperature controller element, the cable floor sensor when installing the electric underfloor heating.
This is one of the most important additional mounting elements and should always be used when installing this type of heating system.
The tube is made of heat resistant Teflon. It is plugged with a stopper at one end. It has smooth internal walls that facilitate the assembly of the sensor and adequate flexibility to prevent crimping and allow easy installation.
It prevents accidental destruction of the sensor during assembly work and enables trouble-free, quick replacement of the sensor in case of its failure.
