Cellular Rubber sleeves 

Our cellular rubber sheaths have the dual function of providing acoustic and thermal insulation, as well as mechanical protection against wear and impact. 

Insulating tubes are used in industrial cooling systems (heat pumps) or as grommets in vehicles, to increase the safety and comfort of household appliances or cars. 

Made-to-measure, our ducts are available in different elastomers, diameters, thicknesses and lengths to meet all your requirements. 

For specific applications, our engineers are on hand to study the feasibility and select with you the solution best suited to your application, guaranteeing excellent acoustic and thermal performance.
