Wear ring that stabilizes piston movement inside Graco airless pump assemblies, reducing internal friction and protecting cylinder surfaces during high-pressure operation.
| Equipment Type | Compatibility Notes |
|---|---|
| Graco Airless Paint Sprayers | Used in select models featuring piston pump assemblies that require a 1.50in ID wear ring specification. |
| Graco Piston Pump Systems | Fits pump configurations designed for a 1.73in OD x 0.50in wear ring dimension standard. |
| Graco Pump Repair Kits | Included in rebuild kits where Graco 020249 is specified as a replacement wear component. |
The Graco 020249 Wear Ring is a precision-engineered sealing and support component used in professional-grade airless paint sprayer pump assemblies. With dimensions of 1.50in inner diameter, 1.73in outer diameter, and 0.50in thickness, it is designed to maintain piston alignment, reduce friction, and protect internal pump surfaces from premature wear during high-pressure operation.
This wear ring plays a critical role in ensuring smooth reciprocating motion within the pump cylinder, helping maintain consistent spray performance and extending the service life of the equipment. It is commonly replaced during routine pump rebuilds or maintenance cycles.
