ROPE PACKING INSTALLATION

- Wrap packing around the shaft, wherever it’s easily accessible, and cut each ring. Or use a mandrel the same size as your shaft to cut rings.
- Install packing in the stuffing box one ring at a time, making sure that you stagger the joints approximately 90 degrees. It is essential that the ends of the rings meet cleanly at the joint. DO NOT ADD GREASE OR OTHER LUBRICANTS-THESE CAN HINDER PERFORMANCE.
