It's very Eheimy, if you think about it. And an improvement
over the smaller model which relies on torque to maek a
compression seal. In the XL model, how hard you twist on
the cap ring doesn't matter. That's the genious of it. They
just started using it later than others.
It's amazing what one can find out if one takes things
apart. I;'m not sure if it was Riachrd Feynmann or Lou Reed
that said that. ;-)
