Zusammenfassung:	A method of making a packing seal comprising compression molding a thermo-setting plastic in a spiral mold so that a partially-cured spiral seal is formed, removing the partially-cured seal from the mold, and winding it on a mandrel of a selected diameter, curing the spiral seal on the mandrel, and removing the seal from the mandrel, whereby the resulting seal is resilient and can be used to seal any part having a diameter within a given range, which range has the diameter of the mandrel as a median.
