A wall entry cuff is a polymer product used to protect the external insulation of a pre-insulated pipeline according to GOST 30732-2006. The product is used to lay a polyurethane foam pipe in a polyethylene shell at the entrances of a pipeline element or an insulated pipe into concrete thermal chambers. The cuff is laid between the external polyurethane foam insulation of the insulated product and the edge of the concrete opening through which the pipe product in polyurethane foam insulation is inserted into the chamber.

Wall entry cuffs are components for laying polyurethane foam pipelines of heating networks and are supplied together with other materials for installation – polyethylene compensation mats and other materials.
