I need to pull some cable through a flexi plastic conduit which is a little on
the tight side - the cable is twin and earth and the conduit is that grey
flexi, convoluted stuff frequently seen on the continent (as it came from
there) and apparently there is a yellow lubricant I think like a thin silicon
grease that eases its way through the conduit.
I haven't got the yellow grease,....

so the question is.... is there a suitable everyday UK alternative ?

Why not use KY Jelly ?

- should be safe on plastics and rubber

.... and guarantee satisfaction
