Stubborn CamLocks

Do camlocks require a bit of a break-in period or do they ever get easier to close with age? I have a few that are a real challenge to close and I have to manipulate the levers on them in such a way to get both of them to close. I may have one that is worse than the others and I may try to replace it but it seems like quite a few of them are somewhat difficult. Is there any way to lube them or something to make them easier to close or is it possible I just got a couple bad connectors?

It's all about the gaskets.
Perhaps you can find some with a thinner profile...

Cheers!

BobbyM sells thinner gaskets.

Thanks guys, didn't even put two and two together to realize the gasket might be an issue. I see a note now on Bobby's page with some tips to try so I'll give those a shot such as keeping them connected for a bit to compress the gaskets some. I'll have to pick up a little keg lube too.
