Abstract
The present invention provides improved retention of O-rings and easier O-ring replacement by using an O-ring retainer in a bar gun. Furthermore, the assembly of the butterfly plates of the bar gun is improved by using molded ball bearing clusters that fit in recesses in the butterfly plates, thus eliminating the welding of the balls to the butterfly plates and the need to purchase such precise and intricately small balls. The O-ring retainer and molded ball bearing cluster are preferably made from bearing quality acetal plastic materials.
