Installation & Usage Tips
- Ensure the machine is fully depressurised and drained before servicing the packing area.
- Clean all sealing surfaces and grooves of debris, scoring or damage — even small imperfections can reduce seal life.
- Lightly lubricate the O‑Ring (using appropriate lubricant for your fluid) to aid installation and avoid twisting or damage.
- Install the O‑Ring so it seats evenly; avoid pinching or misalignment. Re‑assemble the gland or assembly as per the machine’s service manual torque and sequence.

No — you must verify compatibility. While the 108824 is documented for certain Graco pump models (e.g., 17H825, 17H827), it may *not* fit all series. Always refer to the specific machine’s exploded parts diagram or manual to see if part 108824 is listed.
Replace the O‑Ring when you notice persistent leaks around the packing gland, reduced output/pressure from the pump, or during a scheduled rebuild of the machine. It is good practice to inspect the seal’s condition periodically.
