A wrap element and tip seal are disclosed for use in fluid apparatus of the scroll type which include a wrap element having a groove disposed within its tip surface of spiroidal configuration generally conforming to that of the wrap element. A tip seal is disposed within the groove and comprises a relatively rigid strip of material having been wound about its longitudinal axis into a spiroidal configuration generally conforming to that of the groove, the strip of material having a cross section taken in a plane substantially perpendicular to its longitudinal axis wherein at least the radially outer surface thereof is convex in a radially outward direction. This configuration for the tip seal has the advantage that it may be formed using conventional winding techniques wherein a certain amount of "twist" about the longitudinal axis of the strip of material is normally encountered.
