Plastic tube with 28mm internal bore?
25mm plastic conduit (internal bore around 22mm) makes an ideal sleeve
for 15mm copper tube passing through a wall. 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? TIA |
