Abstract A gas valve and mixing tube for a gas burner are hold frictionally together by a plastic bushing which fits around the hood of the valve and within the upstream end of the mixing tube. The body of the bush- ing and a flange thereon maintain adjacent parts of the valve and tube out of metal-to-metal contact to eliminate rattling. The bushing is short enough not to interfere with the primary air inlet opening. In- terior ribs in the bushing permit articulation of the valve and tube to facilitate installation in cramped quarters. The bushing and internal ribs are tapered to facilitate assembly of the three parts. - o -
