All his boats now have the new valve. Reason being, you can pump them up with anything specially the LVM with out having to open them quickly close them. They are super easy. Maybe ordering a spare cap might not be a bad idea, but they are attached with a string. As long as you don't pull on the cap for any reason, they really shouldn't come off. I caught myself trying to lift the boat by the cap...learned quick to not do that. Plus all the boats with the exception of the Traditional two pontoons are bladderless. Much stronger and no zippers to mess with.
