The invention relates to a primary gasket (1) for a cylinder assembly (100), in which the cylinder assembly (100) comprises a cylinder (101) and a float (102) housed in a sliding manner in a float housing (104) delimited by a cylinder wall (103) of the cylinder (101) in order to pressurize a fluid, in which the primary gasket (1) comprises an annular body (2), the annular body (2) is configured to be housed in a primary gasket housing (105) defined in a cylinder wall (103), where the primary gasket housing (105) is delimited radially by an axial housing wall (107) and axially by a first radial housing wall (108) and a second radial housing wall (109), where the first radial housing wall (108) and the second radial housing wall (109) are configured to be housed in a primary gasket housing (105) defined in the cylinder wall (103). The first radial housing wall (108) and the second radial housing wall (109) are connected as undercuts to the axial housing wall (107), where the annular body (2) comprises an inner lip (4), a central lip (5), an outer lip (6) and a back portion (3), where the back portion (3) comprises a back abutment surface (13) configured to abut against the first radial housing wall (108) of the primary gasket housing (105), and where the first radial housing wall (108) and the second radial housing wall (109) are connected as undercuts to the axial housing wall (107). Wherein the inner lip (4), the central lip (5) and the outer lip (6) extend from the back portion (3) in an axial direction (X-X) on a side opposite the back abutment surface (13) and are spaced apart from each other in a radial direction (R-R), and wherein the inner lip (4) is configured to form a dynamic seal and a static seal on the float (102), the outer lip (6) is configured to form a seal with an axial housing wall (107), where the central lip (5) comprises an annular root (14) extending axially between the back portion (3) and a root edge (15), where the central lip (5) comprises a plurality of protrusions (10, 9), where each protrusion (10, 9) protrudes axially from the root edge (15), where the plurality of protrusions (10, 9) are arranged in the axial direction of the central lip (5). A plurality of discharge portions (8) are defined by a plurality of protrusions (10, 9) and a root edge (15), where each discharge portion (8) is defined by each protrusion (10) of the plurality of protrusions (10, 9) and a first adjacent protrusion (9) of the protrusion (10) and by a free edge portion of the root edge (15), the free edge portion of the root edge (15) extending between each protrusion (10) and the first adjacent protrusion (9) of the protrusion (10), wherein each projection (10, 9) extends in the circumferential direction with a projection extension (G), each discharge (8) extends in the circumferential direction with a discharge extension (L), the sum of the discharge extensions (L) being greater than the sum of the projection extensions (G).
