What is the Graco 17D481 Pump Cylinder?
The 17D481 Pump Cylinder is the precision-machined cylinder body for Graco’s piston pump assembly. It provides the sealing and wear surface the piston travels in to generate spraying pressure. Built for durability and smooth operation, it helps maintain consistent pressure, reduces bypass, and extends overall pump life.
Key Highlights
- OEM fit for popular Ultra / Ultra Max II / ST Max families and more (see list above).
- Durable metal construction (stainless/chromed wear surface) for long service life.
- Sealing interface designed to maintain pressure and reduce leakage.
- Includes O-ring (PTFE/Teflon style on many kits) for immediate install in compatible pumps.
