Snap-on stopper, 13×20 mm, Butyl, Gray
: W224100-181
These snap-on stoppers provide maximum sealing for vials with a blow-back glass finish, which is a small ridge on the interior of the vials neck.
- Not recommended for vials with a straight-walled finish
The blow-back feature is typically found in vials from North American manufacturers.
The snap-on stopper locks into the blow-back ridge, providing a tight seal and keeping the stopper from backing out.
