These spiral, stainless steel lock rings (also known as snap rings or retaining rings) will secure a Micromatic valve into the D-system, drop-in Sankey neck.
Keep these on the shelf to ensure your kegs stay in service.
These rings are specifically designed to fit certain valve types. Do not substitute them for other designs! Valves can be pressurized and must be properly secured within the keg neck for safety.
Remove and install using a valve removal tool and lock ring knife (sold separately, links below)
Sold in packages of 25. For example, ordering a quantity of 2 will give you 50 lock rings.
