Products for
 Mechanical & plant engineering

In mechanical and plant engineering, components must function reliably and withstand constantly changing mechanical, thermal, and media-related stresses over the long term.

Lézaud offers Hoses, Round cords, Profiles, Sheets as well as flat seals and O-rings for a wide range of applications in mechanical and plant engineering.

Crucial to this are robust materials, precise sealing function, and a material selection that suits the design. Based on our expertise in plastics, TPEs, and elastomers, we provide targeted advice and develop suitable solutions – tailored to the medium, application area, and technical requirements.
