Flex-Drive Coupling for 10 mm OD Glass Stirring Shafts

This Flex-Drive stirrer coupling eliminates the need to use rubber hosing or universal adapters to attach glass stirrer shafts to overhead motors. The coupling incorporates a 3" long epoxy coated spring to compensate for misalignment and to help isolate breakage. The lower end of the coupling has a Celcon compression nut which secures the glass shaft to the coupling via a silicone rubber insert. The silicone insert, along with the knurled compression nut, permits hand tightening of both ground and polished shafts. The top epoxy coated bushing is fitted with an allen screw and will accept 5/16" O.D. stirrer motor shafts. Adapters to 1/4”, 3/8" and 1/2” are available separately to permit use of coupling with stirrer motors having different drive shaft diameters. Please contact us for pricing and availability.
