Maintenance Tips
During service, ensure the cavity and mating surfaces are clean and free of debris before installing new O‑rings and packings from the kit. Apply light compatible lubricant if required, seat the components properly and verify no torsion or misalignment. After installation, test operation under normal pressure and inspect for leakage. Replace at pre‑determined intervals or sooner if signs of seal fatigue, leakage or reduced performance appear.
Frequently Asked Questions
The kit includes O‑rings and packing seals matched to the specific Graco module to restore seal integrity and prevent leaks.
Install the kit during scheduled preventative maintenance or if you observe leakage, seal degradation or pressure drop in the associated equipment.
