Who would have thought..............?

My local HB shop told me the same thing, but I now use the Coopers seals bought at Coles. They work fine on both roll tops and twist tops.pacman wrote:I am led to believe you can get different kinds of caps, some designed for roll tops, & some for twist tops. My local Ubrew4U guy has shown me caps with slight variations in the designs of their sealing surfaces.
Yep! Even tried them. Roll top caps do not give good seals on twisties, but the twist top caps work fine.
Anyone experienced this?
