CK Gas Savers

[Tigman]

ive treated myself to a couple of CK Gas Savers with perspex cups, I got a small and a large one !
the small one fits together very snuggly but the large one is rather tight on the o ring that is , has any one here got said gas savers and did you use a bit of lubrication to get the cup on and if you did what did you use ?
thanks in advance

Just smear a little bit of spit around it with a finger, should slip right in/on then
