Milwaukee O-ring for 1/2" Drive

(Use with 44-90-4530 Friction Ring)

The 34-40-0900 Milwaukee O-Ring is a replacement retention ring designed for 1/2" drive impact tools, helping keep sockets firmly secured on the tool’s anvil during heavy-duty use. When paired with the Milwaukee 44-90-4530 Friction Ring, this O-ring creates the proper retention system that holds impact sockets in place while still allowing easy removal when needed. It’s a small maintenance component that plays a big role in tool reliability—because a socket that stays attached makes the whole job go a lot smoother.
