Product Description
The Graco 183361 Sleeve Cylinder is an OEM wear component from the fluid section of select Graco sprayers (Ultra, GM and LineLazer families). Over time the cylinder can wear or score, causing packing failure and pressure loss. Replacing the sleeve helps restore proper sealing and pump performance. Using genuine Graco parts maintains durability and compatibility with factory tolerances.
Installation & Maintenance Tips
- Confirm your exact sprayer model, pump type, and series before ordering (serial tag/model decal).
- When replacing the sleeve, inspect the piston rod for wear/scoring and replace packings if needed.
- Reassemble per service manual torque specs; pressure-test and check for leaks after reassembly.
- Flush with compatible solvent after install; use clean, filtered coatings to prolong component life.
Helpful Notes
- Model names may appear in different formats (e.g., GM5000 vs GM 5000); confirm against your parts list.
- If your unit is a variant within the Ultra 1500, GM 5000/10000, or LineLazer 5000 families, cross-check the pump bill of materials for 183361.
