Septa N 20, Butyl/PTFE, Red/gray, 3.0 mm, 50° shore A

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. The septa is a molded Butyl/PTFE septa with only centrical PTFE lamination which is why it seals extremely tightly. It has a temperature resistance of -40 °C up to 120 °C.
