Key Features & Benefits

OEM Part Number: 108824 – ensures correct fit and performance when used with compatible machines.
Function: Acts as a sealing packing O‑Ring in pump assemblies — prevents fluid leakage, maintains pressure.
Reliability: Installed as part of maintenance or rebuilds — helps extend the service life of the equipment.
Maintenance Tip: Before installing, inspect the gland/bore surfaces for wear and clean thoroughly; using the correct O‑Ring reduces downtime and seal failure.

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.
Keep genuine Graco spare seals like the 108824 on hand for scheduled maintenance — reduces unplanned downtime and improves reliability.

Frequently Asked Questions

The O‑Ring functions as a seal within the pump’s packing or gland assembly to prevent high‑pressure fluid from bypassing the rod or piston. A proper seal ensures the pump holds pressure and operates efficiently.

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.

Summary

In short, if you own a compatible machine listed above and your parts manual shows part 108824 as the packing O‑Ring for your pump, then this OEM‑specified seal from Graco is the correct replacement. Be sure to confirm your model match and install it properly to ensure reliable, leak‑free performance.
