Yes! We offer two types of caps without a septa:
The first type is a completely closed cap where the area that would normally have a hole for the septum is covered. These are offered with a Liner instead of a Septa. Please see catalog numbers 9502S-09-SR and 9502S-09-SR-K for examples.
The second type is simply the polypropylene cap in which the septa is Not present. The caps are normally referred to as Open Hole Caps. An example catalog number for this type of cap is 9502S-00-B-M.
