A braided hose which has a frost-free socket joint made by placing a ring of brazing material above the joint and heating the joint below the ring. This way, the brazing material flows into the joint so that its external and exposed edge of the joint is completely filled. If the capillary action of the molten solder is incomplete, any voids in the joint are exposed to the interior of the hose and not to the atmosphere. The socket is very shallow, in the order of one-half to one convolution of the hose.

A chafe or fire sleeve for a hose is an integral coaxial structure having an inner layer of silicone and an outer layer of urethane in the range of 80%-20% urethane and 20%-80% silicone, respectively. The inner hose structure preferably comprises an elastomeric hose covered by braid, with the silicone bonded onto the braid. Five examples of materials are given, ranging from pure urethane to pure silicone and including three exemplary mixtures thereof. Pure urethane provides excellent antichafe, but not fire retardant, qualities; and pure silicone provides excellent fire retardant, but not necessarily as good antichafe, qualities. This particular invention is primarily directed to the fire retardant or fire resisting qualities of silicone, which is an ablative material that forms a refractory ash. The fire sleeve is an ablative material which tends to flake off the hose as it burns. This flaking is a disintegration of the hose which is one of the primary causes of the ultimate hose failure.

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.

A sacrificial anode is made in the form of a disk with a tire made of a sacrificial anodic material. The disk has a central hole which fits over one of two parts to hold the disk in place, as between two telescoping parts, for example. A number of alternative modes of sacrificial anode construction are shown. In some embodiments, conductive or semiconductive plastics are used to provide connections with controlled conductivity.
