A vulcanized reinforced elastomeric hose and a method for its production wherein a layer of uncured rubber supported on a mandrel is surrounded by reinforcement filaments and thereafter vulcanized. In the same method of the invention recesses are provided in the surface of the uncured rubber beneath the reinforcement filaments to accommodate expansion of the mandrel and/or expansion of the uncured rubber and/or shrinkage of the filaments and thereby prevent rubber from being exuded above the reinforcement filaments on curing.
