Wunderbar M4 Bar Gun Repair Kit

Keep your Wunder-Bar® M4 (Mark 4) post-mix bar gun running at peak performance with this complete, professional-grade repair kit. Specially designed for high-volume bar and beverage operations, it gives you everything needed to service your soda gun, reconfigure flavors, and get back to pouring without waiting on a service call.

Whether you're swapping button flavors, converting positions between carbonated and non-carbonated, or troubleshooting ratio problems, this kit puts the right parts and tools in your hands.

What this repair kit lets you do:

• Change button flavors – reassign product positions on your M4 manifold quickly and accurately.
• Swap butterfly plates – convert carbonated and non-carbonated configurations using the stainless-steel butterfly plates that set your dispenser's product layout.
• Verify Brix ratios – includes a syrup separator nozzle so you can confirm an accurate syrup-to-soda ratio and protect drink quality.
• Handle on-the-spot repairs – the essential components and service tools to perform most M4 bar gun repairs in-house.

Because downtime behind the bar means lost sales, it's always smart to keep a repair kit on hand before an emergency strikes. Stock one with your spare parts inventory and you'll be ready the moment a gun needs attention.
