Aijiren’s Septa has different thicknesses for different materials. For example, the thickness of PTFE/Silicone double-layer Septa is 1.5mm and 1.3mm, and the thickness of PTFE/Butyl double-layer Septa is 1.6mm. It is certain that septa with different thicknesses has a good sealing effect when tightening the cap.
