Septa N 8, Silicone/PTFE, White/red, 1.3 mm, 45° shore A 70248

Replacement septa are not offered for all cap types and sizes, as manual assembly is not recommendable due to contamination risk and possible wrong side orientation. Nevertheless, for the most common sizes and septa materials we offer them along with the appropriate empty caps. Single septa N 8 can only be used in screw caps N 8; they are not suitable for crimp caps N 8. Please consider that the nominal diameter of the septa sometimes might be smaller than the ND of the cap due to the cap's wall thickness (e.g. N 12 septa are asembled in to N 13 screw caps).
