         2 . The sleeve insert of  claim 1 , wherein the molded predetermined pattern comprises a plurality of ribs and elevations. 
     
     
         3 . The sleeve insert of  claim 1 , wherein the molded predetermined pattern comprises a plurality of slits passing through the body in a direction longitudinal to the body. 
     
     
         4 . The sleeve insert of  claim 1 , comprising a generally cylindrical body, wherein the bulk has a generally cylindrical shape. 
     
     
         5 . The sleeve insert of  claim 1 , wherein the molded foam material comprises polyurethane. 
     
     
         6 . The sleeve insert of  claim 1 , wherein the molded foam material comprises an intumescent material. 
     
     
         7 . An air, acoustic and/or fire sealing device comprising:
 (a) the first air, acoustic and/or fire sealing insert of  claim 1 , wherein the body has an outer diameter, and the body is adapted to allow one or more pipes, fibers and/or cables to pass through the first and second ends and the bulk; and,   (b) a hollow sleeve having an inner diameter, a first open end and a second open end, the ends being axially arranged;
 wherein the first air, acoustic and/or fire sealing insert is arranged in the sleeve. 
   
     
     
         8 . The device of  claim 7 , wherein the first air, acoustic and/or fire sealing insert is arranged in the first open end of the sleeve. 
     
     
         9 . The device of  claim 7 , wherein the molded predetermined pattern of the first air, acoustic and/or fire sealing insert faces outwardly from the first open end of the sleeve. 
     
     
         10 . The device of  claim 7 , wherein the molded predetermined pattern of the first air, acoustic and/or fire sealing insert faces inwardly from the first open end of the sleeve. 
     
     
         11 . The device of  claim 7 , wherein the outer diameter of the first air, acoustic and/or fire sealing insert body is greater than the inner diameter of the hollow sleeve. 
     
     
         12 . The device of  claim 7 , wherein the outer diameter of the first air, acoustic and/or fire sealing insert body is less than or equal to the inner diameter of the hollow sleeve. 
     
     
         13 . The device of  claim 7 , further comprising a second air, acoustic and/or fire sealing insert, arranged in the sleeve. 
     
     
         14 . The device of  claim 13 , wherein the second air, acoustic and/or fire sealing insert is arranged in the second open end of the sleeve. 
     
     
         15 . The device of  claim 13 , wherein the molded predetermined pattern of the second air, acoustic and/or fire sealing insert faces outwardly from the second open end of the sleeve. 
     
     
         16 . The device of  claim 13 , wherein the molded predetermined pattern of the second air, acoustic and/or fire sealing insert faces inwardly from the second open end of the sleeve. 
     
     
         17 . The device of  claim 13 , wherein the outer diameter of the first air, acoustic and/or fire sealing insert body is greater than the inner diameter of the hollow sleeve. 
     
     
         18 . The device of  claim 13 , wherein the outer diameter of the first air, acoustic and/or fire sealing insert body is less than or equal to the inner diameter of the hollow sleeve. 
     
     
         19 . The sleeve insert of  claim 2 , wherein the molded foam material comprises polyurethane. 
     
     
         20 . The sleeve insert of  claim 5 , wherein the molded foam material comprises an intumescent material.
