Graco's Fusion ProConnect Round 02 Mix Chamber is protected by a robust Chromex coating that resists wear, corrosion, and chemical damage. This coating extends the lifespan of the chamber while maintaining optimal functionality over time. An alignment groove ensures proper assembly every time, preventing misalignment that could lead to damage or decreased performance. Designed to slide into position smoothly, the mix chamber reduces the risk of damaging side seals, ensuring a reliable and long-lasting spray system.
