Hi,

I'm painting the outside of my house and in the general clean-up I
want to replace a purely cosmetic part of the boiler flue arrangement.
It's a co-axial flue for a combi which emerges horizontally through
the wall. The bit I'm looking for I would call a shroud or a skirt (or
possibly a grommet). It's a rubbery round thing that slides over the
flue on the outside of the house and covers the rather untidy edges of
the hole in the wall where it emerges. It was once white and now it's
browny grey and has to go. But I can't find the right word to pull up
what I want in google.

Thanks for any assistance,

Martin
