The 34-40-1880 Milwaukee O-Ring is a replacement retention ring designed for 1/4" drive impact tools, helping keep sockets and accessories securely attached during operation. When used together with the Milwaukee 44-90-1070 Friction Ring, this O-ring provides reliable socket retention on the tool’s anvil, preventing sockets from slipping off during demanding work. It’s a small but important maintenance part that keeps your impact tool performing the way it should—because the only thing that should spin during a job is the fastener, not the socket flying off.
