I'm not sure it needs it really Steve. .. the new one I mean it's a combination of age deterioration and possibly over tightening. I don't remember the exact size now but an interior metal sleeve lie you slip in the modern poly prop water pipe fittings would probably help. ..although they are too small from my vague recollection but an internal sleeve would aleviate any possibility of over tightening and hence crushing the pipe onto the spigot. ...
But If careful I think t will be fine for years to come
