Abstract
Abstract A method of providing an end fitting in the end portion of a hose, by forming a mould around the hose end portion, so that the end portion is a part of the mould, and then injecting a hardenable material into the mould so that the moulded part is moulded to the end portion. The bore of the hose may be closed by a removable plug prior to the moulding. An end fitting nut may be positioned around the end portion to form a part of the mould, and the nut may be threaded on the plug; prior to the plug being used to close the bore of the hose.
