Sleeves are made of steel, plastic, or other materials that could be used to stop the fire from spreading. The major purpose of sleeves is to create a protective cover for a pipe, preventing the heat influence, and preventing the fire from spreading via a piping system. Additional function, even though not designated as the main one but very important nevertheless, is preventing any damage to the tubes in case of the deformation of the surrounding material. In addition, sleeves often have firestop systems. We offer a wide range of sleeves and supplementary parts. Choose from affordable and reliable products on Mega Depot!
