I have an original expansion boittle on my Stag, no worries about that except that when I was tightening the pressure cap I felt that the brass fitting on the top of the bottle moved slightly. Examining the structure, it seems that the plastic bottle has a lip moulded to the top edge and the brass top is peened over that lip to seal the bottle and therefore the system. I wonder if there's a known adhesive or sealant that I could run in between the plastic and the brass to make sure it doesn't move again or leak? Making a die to peen the edge over some more is do-able but I'd rather use the time doing something more interesting!

…. Clean clean & clean again. Dry in oven at 50 -60 deg C.
Use superglue in the joint with the bottle upside down.
pressure test.
Should not need activator because of copper presence.
Can also use activator though.
There is a rubber seal in the collar…. Clinching poor & seal perished…. However, new bottles are not that good.
I do have a spare bottle here.
It’s possible that this joint is largely responsible for much of the stag’s reputation & also (one) unknowing reason that header tanks get bought too.
oops I’ve said it now! -
I had 3 new expansion bottles all proved faulty, ie split on seam, so i fitted a Header Tank EJ Wards, no problem since.Originally posted by jbuckl View PostComment
