The friction ring is the metal retaining ring secured on the 1/2 in. impact wrench anvil that works together with the O-ring beneath it to hold sockets in place on the anvil during impact driving and loosening operations. The friction ring seats in the anvil groove on top of the O-ring when a socket is pushed onto the anvil, the friction ring and O-ring assembly deflects inward and then snaps back to lock the socket’s retention groove, providing the tactile “click” engagement that holds the socket securely during high-torque impact operation. A worn, stretched, or broken friction ring that allows sockets to fall off or disengage from the anvil during use requires replacement to restore proper socket retention. A screwdriver and pliers are required for replacement.The friction ring should be replaced together with the anvil O-ring for best results both are wear items that degrade with extended use. Always verify your catalog number and serial number before ordering to confirm this is the correct friction ring for your specific impact wrench model.FeaturesGenuine Milwaukee OEM 1/2 in. friction ring for select Milwaukee 1/2 in. impact wrenches verify by serial numberCompatible with 2555-20, 2663-20, 2755B-20, 2763-20, 2767-20, 2861-20, and 9071-20 among othersMetal ring secured on anvil to retain sockets during high-torque impact driving and looseningScrewdriver and pliers required replace with anvil O-ring for complete socket retention restorationVerify catalog number and serial number before ordering to confirm correct model compatibilitySpecificationsType: Friction Ring (1/2 in.
