Description
The Micro Matic 1.25″ O-Ring is a critical maintenance component for maintaining a 100% gas-tight seal in German ‘A’ System keg couplers. Precision-molded from high-durability, food-grade elastomer, this O-ring ensures a pressure-safe interface within the coupler body. A worn or flattened O-ring is the primary cause of slow gas leaks and inconsistent beer flow in high-volume import draught systems. Essential for any technician’s service kit for maintaining premium European lager taps.
Technician’s Repair Tip: Always keep 5-10 of these in your service kit for ‘A’ system kegs. When replacing, ensures the internal coupler surfaces are clean of “beer stone” or mineral scale. Apply a tiny amount of food-grade silicone grease (Petrol-Gel) to the O-ring to ensures a perfect seat and prevents the rubber from bunching or tearing during reassembly. This is a genuine Micro Matic OEM replacement part.
