A method of manufacturing a tubular element that has a sealing gasket arranged around its external surface comprises the steps of: providing a continuous sealing strip; forming the sealing strip into a shape that essentially corresponds to a perimeter of the tubular element; cutting the sealing strip into a sealing strip portion having a length that essentially corresponds to the perimeter of the tubular element; joining together a first and a second end of the sealing strip portion, so as to form the sealing gasket; and fastening the sealing gasket around the perimeter of the tubular element. An apparatus for manufacturing such a tubular element has means for carrying out the steps.
