I'm trying to replace the pan collar seal on a vario connector and there seems to be a difference between the new seal supplied by Reece and the one I bought from Bunnings.
I cant seem to get the collar to push back on over the seal and stay on.
Should either seal be a suitable replacement or is there a particular seal for the vario collars and secondly is there a requirement to use some sort of type solvent or glue to hold the collar on?
