Usage Notes & Tips

Confirm your sprayer is a cart version (not a stand). This kit is tailored to cart frames.
After conversion, always use lacquer-rated hose, tip, and gun packings.
Flush thoroughly with the manufacturer-recommended solvent after each use.
Do not mix water-borne and solvent systems without a complete flush.

Frequently Asked Questions

No. The 17J873 is specified for cart models. Stand frames typically require a different lacquer kit or are not intended for lacquer conversion—verify your exact model before ordering.

ProX21 sprayers are generally lacquer-ready out of the box, so this kit is usually not required.

Use lacquer-compatible tips, hose, and ensure your spray gun packings are solvent-rated. If you switch back to water-borne coatings, flush thoroughly before and after use.

The kit primarily adds solvent compatibility. Pattern quality depends on tip size, pressure setting, material prep (reduced/strained), and gun technique.

Check the data plate on your sprayer for the exact model (e.g., ProX17 Cart). If unsure, share your model/serial with support and we’ll verify fitment for the 17J873.
