ABSTRACT:
A heat-resistant hose for transport of high temperature fluid, wherein the inner surface of the hose in contact with said fluid comprises a material containing blended rubber of fluorinated rubber (FKM) and acrylic rubber (ACM). In particular, a heat-resistant hose for transport of fluid containing high temperature oil which comprises an inner tubular body composed of one or more layers at least the most inner layer of which consists of blended rubber of FKM and ACM, fiber reinforcements wound around the outer surface of said inner tubular body the thread extracting force of which the fiber reinforcements is not less than 1N/mm, and an outer tubular body composed of one or more layers bonded on the surface of said fiber reinforcements, said most inner layer preferably containing carbon black having the value (A.times.B) of not more than 3500 obtained by multiplying the value A of nitrogen adsorption specific surface area (m.sup.2 /g) by the value B (PHR) of part by weight of amounts of carbon black used is added to the blended rubber.
