Abstract
Abstract An elongated insulating cover of high temperature resistant cloth is impregnated on one side with a fluid sealing high temperature resistant flexible coating, and is covered on the other side with a metallic coating. Fasteners are secured along both sides of the cover; which cover is then overlapped around aircraft flammable fluid lines with the fluid sealing flexible coating on the inside, and the fasteners joined together.
