I have a few camlocks that i bought a year or two ago. I'm just now getting my brew stand together. As im checking all the connections i find that the cam ears on the femal pieces are reall tough to close. There is an orange/red o-ring in the female connection. Is there a good way to help break these cam fittings in? Should i look at replacing o-ring with gasket that might be thinner or softer? I saw some replacement gaskets bargain fittings and was thinking of trying them but though I'd ask you guys first.
