In a process for making a gasket with a tubular shape, a tubular blank of elastomeric material is extruded and zones are marked along its length, the zones corresponding to a location along the length of the gasket which is to undergo a change of shape, dimension, or orientation through a shaping operation. The shaping operation involves a preliminary step of attaching a U-clip to the blank and introducing the blank, with the U-clip attached to it, into a shaper passage which has a guide element extending into the passage, and guiding the blank through the shaper passage while the guide element extends into the U-clip.
