When installing packing rings, how much should the cut ends be staggered?

When installing packing rings, staggering the cut ends by 90 degrees is crucial for optimal sealing and performance. This staggered arrangement helps prevent leak paths from forming. If the cut ends were aligned or set at 0 degrees, there would be a direct line for any potential leaks between the packing material and the shaft.

Staggering the cuts at 90 degrees ensures that each packing ring covers a different section of the working surface, reducing the likelihood of leaks and improving the overall integrity of the seal. Additionally, this configuration helps distribute the load evenly across the packing rings, thereby enhancing their effectiveness and extending their service life.
