A powder-metallurgically produced piston body for a piston-cylinder arrangement, in particular a shock absorber piston, has a one-part piston body, a revolving or circumferential web that protrudes radially outwardly from outer surface of the piston body, longitudinal webs, and at least one traverse groove. A collar-shaped seal, made of thermally deformable material, is formed onto the piston body such that the revolving or circumferential web and the support webs are formed into the seal over at least a part of their heights.
