Frequently Asked Questions

A worn gland can lead to fluid leaks, reduced pressure, and loss of pump efficiency. Severe wear can damage other packing components.

It is not recommended. Genuine Graco parts ensure correct dimensions, sealing, and performance. Non-OEM parts may fail faster and affect warranty.

Replacing the gland is straightforward if the pump’s service manual is followed: remove packing nut, replace gland and packing, stack V-packing rings correctly, and torque the nut.

Replacement depends on usage, materials sprayed, and maintenance habits. Check the gland during pump rebuilds or when leaks/performance issues are observed.
