Abstract
A bush for a valved closure unit of the kind used in beer kegs comprises two-parts and when in a unit engages an opening in the keg. One part of the bush which engages the opening, is in the form of a hot brass stamping or stainless steel or aluminium casting. The other part of the bush is of stainless steel and is held in the first part by an interference fit and/or interfitting ribs and grooves and/or adhesive. The interstices between the parts are sealed by a sealant. A closure unit employing such a bush has a valve seat formed by an internal flange on the second member and a valve is guided as it moves towards and away from the seat.
