Frequently Asked Questions

A packing nut applies pressure to the packing seals, helping them form a tight seal around the moving rod or piston. This reduces leakage and supports consistent pump performance.

Yes. The stainless steel construction offers good resistance to corrosion, making it suitable for many industrial fluids and harsh operating environments.

A packing nut should be inspected during routine maintenance and replaced if it shows signs of wear, damage, or if it can no longer maintain proper packing compression.
