Well Made & Wide Application: 304 stainless steel and food-grade silicone, durable and rustproof keg coupler adapter kit. This ball lock keg conversion kit fits all 5/8-inch thread A, G, S, and D type keg couplers. Compatible with standard beer keg couplers. Easy to Convert and Clean: Quickly convert your keg in seconds. Simple toggle operation. Rinse posts by infusing and dispensing clean water through the keg—no disassembly required. Identification and Assembly: A subtle etched line around the top of the gas post aids identification. Tighten posts by hand or with pliers. Do not over-tighten, as this may deform washers and cause leaks. Enables convenient switching between commercial kegs and homebrew CO2 tanks. Tips: - Rinse posts by dispensing clean water from the keg. - Do not disassemble the adapters—they are difficult to reassemble. - Do not over-tighten; hand-tight is sufficient for a proper seal. Color: Black, White, Silver Material: Plastic and stainless steel Package Contents: - 2 adapters - 2 rotating nuts - 2 straight-thread replacement heads - 2 distributor connectors Note: Item color may vary slightly due to lighting and screen settings.
