Constructed from high-grade 304 stainless steel, this adapter is built to provide an airtight, flavor-neutral connection in professional draft systems. Its stainless steel construction makes it exceptionally resistant to pitting and corrosion, ensuring a long service life even when exposed to high-acidity beverages like wine, cider, or sour beers.

Technician’s Note: The B409 is an essential “bridge” component when you are upgrading or customizing a system using G408 or GTL425 series couplers. Because it is solid 304 stainless steel, it is the best choice for “clean” dispensing; unlike brass adapters, it won’t impart a metallic taste to your product. When installing, we recommend a light application of food-grade lubricant on the threads to ensure a smooth connection and to prevent galling during future maintenance.
