Description
The Wunder-Bar FR-14-E is a high-performance EPDM O-ring engineered for the flow regulator manifolds of professional post-mix bar guns. This specialized seal is designed for dual-purpose application: it serves as the critical interface for the tube retainer and as the primary seal for the stainless steel (SS) cylinders within the regulator block. Manufactured from food-grade EPDM (Ethylene Propylene Diene Monomer), the FR-14-E provides exceptional resistance to the corrosive effects of carbonated water and high-sugar syrups, ensuring a pressurized, leak-proof environment for consistent beverage dispensing.
- Model Number: FR-14-E (Genuine Wunder-Bar™ Part)
- Material: High-Grade EPDM (Food-Safe & Chemical-Resistant)
- Dual Application: Fits both the Tube Retainer and the Stainless Steel Cylinder seals
- Compatibility: Designed exclusively for Wunder-Bar™ Flow Regulator Manifolds
- Seal Integrity: Precision durometer rating for high-pressure CO2 and syrup lines
- Durability: Engineered to withstand thermal expansion and frequent cleaning cycles
- Function: Prevents internal manifold leaks and maintains precise brix/ratio control
Technician’s Note: The FR-14-E is a “wear item” that should be inspected whenever you perform a manifold teardown. If you notice “syrup weeping” from the back of the manifold or if the tube retainer feels loose, these O-rings have likely flattened or taken a “set.” When installing, always apply a thin coating of food-grade silicone lubricant (like Petrogel or Haynes Lubri-Film) to the O-ring. This prevents the rubber from pinching or tearing during the insertion of the stainless steel cylinder, which is the most common cause of immediate post-repair leaks.
