Well Made & Wide Application: Made from 304 stainless steel and food-grade silicone, this solid and rustproof keg coupler adapter kit is designed for durability. The ball lock keg conversion kit fits all 5/8 inch thread A, G, S, and D type keg couplers and works directly with beer keg couplers. Easy to Convert and Clean: Quickly convert your keg in seconds with simple operation. To clean, flush clear water through the keg and discharge it to rinse the posts. No disassembly required. Identify & Assembly: Features a clearly etched line around the top of the gas post for easy identification. Use hand or pliers to tighten the posts. Do not over-tighten, as this may deform the washers and lead to leaks. This conversion kit allows for convenient switching between commercial kegs and homebrew CO2 tanks. Tips: - Flush clear water through the keg to clean the posts. - Do not disassemble the adapters, as reassembly may be difficult. - Do not over-tighten; hand tight is sufficient for a proper seal.
