The Wunder-Bar Brix & Shutoff Screw O-Ring is a critical replacement seal for commercial soda bar guns. This tiny but essential O-ring (PM10-6-E) ensures a pressure-tight seal for the calibration screws within the manifold, preventing syrup leaks and ensuring consistent brix ratios. Constructed from high-durability, food-safe elastomer, it is designed to withstand the constant pressure and acidic nature of soda concentrates for long-term reliability in high-volume bar environments.
Technician's Repair Tip: If your soda gun is "creeping" or dripping from the manifold adjustment ports, this O-ring is likely worn or flattened. When replacing, ensures the screw threads are clean of syrup crystals. Apply a tiny amount of food-grade silicone grease (Petrol-Gel) to the O-ring to prevent it from pinching during installation, ensuring a perfect 100% airtight seat.
