Description
The Wunder-Bar M4 Butterfly Retainer is a specialized internal component for commercial soda bar guns. This gray retaining plate (PH10-8-M4) is designed specifically for the M4 series manifold, securing the butterfly actuator assemblies within the gun handle to ensure that beverage valves maintain perfect alignment for a drip-free operation. Constructed from high-impact, moisture-resistant polymer, it is engineered to withstand the constant activation and high pressures of professional high-volume bar environments.
Technician’s Repair Tip: If your M4 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.
