Abstract: An improved hose splice and a method and apparatus for field splicing large bore hose are disclosed. In the method, the hose covering material is removed to expose the underlying reinforcing material and the ends to be spliced are buffed preparatory to applying the splicing materials. The hose ends are mounted on a unique plaster mandrel that has a sealing elastomer wrapped in a groove at its midsection and uncured elastomeric packing is forced into the juncture of the abutted hose ends. A reinforcement textile fabric material having elastomeric gum on both surfaces is wrapped about the splice area followed by a suitable covering elastomer. The splice area is wrapped with cure and heat tapes and the splicing materials are vulcanized into an integral structure with the existing hose components. The plaster mandrel is finally broken into small pieces that may be washed out of the hose bore upon completion of the vulcanization.
