Abstract

A hose (such as an airplane fuel line hose) is made from a material which forms ablative particles in the presence of fire. Normally, these particles flake away from the hose. According to the invention, an encapsulating basket weave, braid or cage of stainless steel wire surrounds the hose to capture and retain ablative particles, so that they continue to provide an insulating quality for the hose and, therefore, to prolong the life of the hose.
