Abstract
A universal sleeve for use in an air recirculation barrier to seal off the passage of air around penetrating components comprising a flexible piece of material joined along two edges to enclose the components passing thru the barrier. The engaging edges of the flexible material has Velcro tape of hook and pile construction to closely surround penetrating components and limit the passage of air along the components thru the barrier. Sealing tape may be used on the edges of the flexible material to further seal off the passage of air.
