This kit is essential for these models, as they are originally configured to handle a variety of interior and exterior water and oil-based coatings, but not solvent-based lacquers. Notably, the Magnum ProX21 model already comes equipped to spray solvent-based lacquers and does not require this conversion kit.
The Graco 17L305 is a factory Lacquer Conversion Kit for Magnum stand-frame sprayers. It replaces standard pickup and sealing components with solvent-compatible parts so your unit can spray lacquer finishes and flush with lacquer thinner without swelling or damage.
Ideal for fine-finish projects that call for solvent-based lacquer—cabinetry, trim, doors, furniture, display fixtures, and other interior woodwork where a smooth, fast-drying finish is critical.
Note: Magnum ProX21 is already configured to spray solvent-based lacquer and does not require this kit.
As part of your maintenance plan for graco paint sprayer parts, this kit is a smart upgrade when you need lacquer capability. If you’re gathering graco sprayer repair parts to boost performance or to repair sprayer pump priming consistency, you’ll find everything you need at SprayersAndParts.com.
