Inline p trap

[Routemaster]

I think these Inline P Traps are out of the UK and AU had to clean ours out, there is a rubber tube in that top part that fits... I think between the O seal flange trapped by the top nut when done up and this one is manky anyone seen where to find the inside part? I put it back together and so far no leaks.
Den.
