This style is not recommended for vials with a blow-back feature, which is a small ridge on the interior of the vial’s neck.

The manufacturer that we used for many years stopped making the PTFE faced stoppers available in smaller quantities, so we had to find another supplier. Have ordered these twice now, and they seem to be of very good quality. The only reason for four stars instead of five is that the stoppers are packed in bags of 100, which is fine, but they are not marked in any way as to a part number or description of the product. That just makes me a little nervous, although they definitely have been the correct item.
