This is to fill in gaps in other reviews I've read, you know how I think it's thinner is or I think. I took the photos as a visual aid to the photos with two seals, one came with my gear, the other is the seal. They are thinner and made from the same type of silicone. Because of the difference in thickness, they appear more flexible or less stiff. I currently have three installed. I will only update this if I encounter any quality issues. Hope that helps
