25mm plastic conduit (internal bore around 22mm) makes an ideal sleeve

I've looked and looked over the years but never found anything with
quite such a good fit for 22mm tube.
There's about 3mm all round a 15mm tube with 25mm conduit. Based on
that the tube needs to be around 28mm internal dia or 31mm o/d.. 32mm
waste is around 35 o/d - rather more play than ideal.
Any suggestions please?
28mm Hep20, but expensive unless you have offcuts
