These septa feature a center layer of soft silicone<br />
rubber for good resealing and two harder rubber outer<br />
layers for long life. The soft inner layer clings to the<br />
syringe needle and returns quickly to its original shape<br />
when the needle is withdrawn to prevent “blow back”.<br />
