According to UK site :-
Spigot dia 11.90mm - hole could well be BS611 spec of 12.0mm
O-ring groove dia 9.60mm - more than BS611 specs of 9.0mm
Old o-ring width 8.60mm. If anything, it would be wider than originally due to having been squashed.
New o-ring width 8.70mm - not quite BS611 specs of 8.78mm
Old o-ring on fitting 12.1mm
New o-ring on fitting 12.5mm
