Topband: Help installing compression connectors

[Tony K1AMF]

Anyone have any suggestions on how to install compression connectors on flooded RG6 quad shield coax with PE jacket?   I'm using Belden Snap-N-Seal RG6QS compression connectors but they're nearly impossible to slip on far enough.  I've tried removing the outer  braid and foil and still no luck.  Maybe I should be using different connectors?  The coax I'm using for the beverage is Commscope F6SSEF / 4561804. 

Thanks,
