Annular seal for masonry cavity - consists of elastomeric ring with cuff, reinforcement sealing rim and contact flange

摘要

The annular seal (3) for an opening in a structure (2) through which goes a cable, pipe (12) etc., is made of elastomeric material and is fixed (21) to the pipe (12) with axial expansion. The reinforced sealing-edge (4) at the same time rests against the wall of the structure (2). The cuff-part of the annular seal (3), preferably its axial end, is fastened by a connection (14) to the pipe (12). The seal () has a contact flange (10) on its end axially opposite the reinforcement rim (4). The radial outer diameter of the seal (3) is larger than the radialinner diameter of the hole (1). USE/ADVANTAGE - The elastic seal for an annular space adapts to irregularities in the memory.
