The Wunder-Bar Butterfly Retainer is a specialized internal component for commercial soda bar guns. This retaining plate (PH10-8) secures the butterfly actuator assemblies within the gun handle, ensuring that the beverage valves maintain perfect alignment for a drip-free operation. Constructed from high-impact, moisture-resistant polymer, it is designed to withstand the constant activation and high pressures of a professional bar environment. Essential for any technician performing a full gun rebuild on standard Wunder-Bar post-mix systems.
Technician's Repair Tip: If your soda gun handle feels "loose" or the button alignment is off, the butterfly retainer may be cracked or fouled with syrup residue. When performing a rebuild, ensures all internal O-rings are lubricated with food-grade silicone grease (Haynes Lubri-Film) before securing the retainer. This genuine Wunder-Bar part restores the structural integrity and responsive "snap" of the button assembly.
