Description
Flexible PTFE stirring coupling for shaft 14 mm is a laboratory connector designed to link a stirrer motor with a stirring shaft while allowing limited flexibility. The PTFE construction supports chemical resistance in typical laboratory environments and helps accommodate minor axial or angular offsets during operation. Intended for shafts of 14 mm diameter, the coupling belongs to the family of stirring and quick-connect couplings used in chemical, pharmaceutical and life-science laboratories. It enables reliable torque transmission for routine mixing, dissolution and suspension tasks without rigid metal-to-metal contact at the interface. Supplied as a single piece, the component integrates readily into existing overhead stirrer setups. The flexible PTFE design from manufacturer Witeg is suited to applications where vibration damping and chemical inertness are advantageous. Categories include stirring couplings and quick-connection couplings for laboratory use. Pack size is one piece, ready for immediate installation on compatible 14 mm shafts.
This article is part of Stirring shafts, propellers & impellers, in Stirring, shaking & mixing.

Questions about Couplings flexible PTFE for shaft 14 mm
What is this article?
Couplings flexible PTFE for shaft 14 mm is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Stirring shafts, propellers & impellers, inside Stirring, shaking & mixing, in Instruments de précision.
A shaft, a propeller or an impeller is the wetted end of an overhead stirrer. The diameter and the pitch decide whether the liquid turns over. The material, stainless steel or PTFE, decides what the liquid may be. The chuck size has to match the stirrer.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
