Product Description
The Graco 15A981 Cylinder Seat is an OEM‑specified sealing component engineered to provide a precise, reliable seating surface within a spray gun’s cylinder assembly. It ensures optimal interaction between the piston and cylinder, maintaining fluid control, consistent spray pattern and minimal leakage at the tip interface.
Manufactured to tight tolerance specifications and from durable material compatible with paint coatings and solvents, this cylinder seat supports long‑term performance even under repeated cycles of high pressure, abrasive coatings or high‑speed operation. It is an essential wear‑part when servicing V‑tip or auto‑air assist spray guns, restoring the original factory sealing and alignment.
Key Features

Installation & Maintenance Tips
- Depressurize and fully drain the spray gun before disassembling the cylinder housing to protect against injury or damage.
- Remove the worn or damaged cylinder seat and inspect the piston, cylinder wall and sealing surfaces for scoring or corrosion — replace these if found.
- Lubricate any O‑rings or dynamic seals in accordance with manufacturer guidelines and ensure the new seat is seated flush without tilting or misalignment.
- Reassemble the cylinder carefully, ensuring all fasteners are torqued to specification to avoid distortion of the seat or misalignment of the piston path.
- After assembly, cycle the spray gun at low pressure initially to verify smooth operation, zero leak paths at the tip, and consistent spray pattern before returning to full production use.
