plastic tubing, like most flexible tubing, is identified based upon OD, not ID. A 1/4" nylon tube should be .250 OD. The ID will vary somewhat, but most of it is 1/8" or .125 to 130. A 133 sleeve will not easily fit in a 125 ID Nylon tube. All of the Vans brake systems use 1/4" tubing. It is ok if your insert slides in without force, as long is it is snug and looks like it is a size match. The ferrule ID will shrink and squeeze down the nylon tube when you tighten the nut.
