Also disclosed is an extrusi head for extruding the sealing joint, comprising a die having a central core and an outer bored body spacedly surrounding the core to define therebetween a passage for the extrusion of an elongated tubular member. The outer body is formed along a portion of its bore with contiguous lip-forming grooves opening into the extrusion passage. A diaphragm plate is in contact wit the outer body and has an inner surface corresponding in shape with the bore portion of the outer body and is formed with like contiguous grooves defining lips therebetween. The diaphrag plate lie over the grooves of the outer body to obturate them an a position wherein the lips lie away from them to liberate them for the extrusion of flexible lips over a predetermined length of the tubular member.
