???? Frequently Asked Questions
This packing set is specifically for piston rods with a nominal diameter between 3 to 5 inches — ensure your pump uses that size before ordering.
By renewing the packing around the large‑diameter rod, you restore correct sealing, reduce leakage and rod wear — all of which improve output consistency and service life.
No — it is specifically sized for 3‑5″ diameter rods. Using it on smaller rods will lead to improper sealing and may cause performance issues.
