Comes with a replaceable Teflon sleeve for use with glass stirring shafts. The 4 inch length allows for angular and parallel misalignment of shaft without danger of breakage. The rubber sleeve body absorbs shock and provides quiet-running and vibration-free operation with great torsional stiffness. Corrosion resistant metal, neoprene rubber and stainless steel set screw provide long life in difficult environments.

Only the replaceable Teflon sleeve makes contact with the glass shaft
