Original Makita dust seal sleeve — part number 424665-8 . This molded polymer sleeve seals the nose/spindle area of Makita drywall screwdrivers to keep drywall dust and debris away from internal seals and bearings, restoring smooth operation and preventing premature wear. Supplied as one piece (1 PC), it fits Makita DFS250 series and DFS452 series (including DFS250RTJ and DFS452Z / DFS452 ).
