The O-ring is the small rubber sealing ring that sits in the groove of the impact wrench anvil beneath the friction ring. Together with the 3/8 in. friction ring (44-90-1050, sold separately), the O-ring maintains the friction ring’s position in the anvil groove and ensures that sockets snap on securely and are retained correctly during impact driving operations. A worn, cracked, or missing O-ring allows the friction ring to shift or fall out of position, causing sockets to slip or disengage from the anvil during use. Replacing the O-ring and friction ring together restores proper socket retention on 3/8 in. Milwaukee impact wrenches and drivers.To install, clean the anvil groove, slip the O-ring into the anvil groove, then seat the friction ring over it.
