“Received the items looked like good quality but the 40mm nominal bore plug has a diameter of 43mm. Not much good as I cannot get it into the pipe to begin with to begin expansion sealing.
Waste of money as it does not fit! Disappointing! So unexpanded diameter measures 43mm, fully expanded it measures 50mm. So it would be good for sealing something like a 46 NB pipe, definitely not a 40mm.”
