Functioning and principle of Functioning and principle of LebitLebit

Lebit is thermo-elastic that is a liquid when cast and Lebit is thermo-elastic that is a liquid when cast and hard and elastic when cooled.hard and elastic when cooled.

When used in heating pipes, the product creates a When used in heating pipes, the product creates a flexible section where it is applied, while the hard flexible section where it is applied, while the hard sections remain in place just a few centimetres sections remain in place just a few centimetres further.further.

This hard and flexible combination can be repeated This hard and flexible combination can be repeated indefinitely in the pipes. The properties of Lebit never indefinitely in the pipes. The properties of Lebit never change.change.
