Use them for marine applications and they work well. I used to have a box with different lids and replaced it with this box. They fit well in most sizes, they don't feel flimsy or anything. I've used them to unclog some vacuum lines and they're holding up really well for that. no problems so far. I want to see a list of single size replacements when a certain size runs out.
