MANUFACTURED IN THE USA

13mm SNAP ON style vial stoppers, gray chlorobutyl rubber, for vials with a 13mm crimp finish and American style blowback ring in the neck.

13mm snap on vial stoppers offer the best sealing for serum vials manufactured with a blow-back glass finish. A "blow-back" neck  finish is a small ridge on the interior of the vial neck. These snap-on stoppers lock into the blow-back ridge, allowing for a more secure seal and helps prevent the stopper from popping back out.
