## Questions & Answers

**Q: "Why does the gauge show high pressure when I'm not spraying, but drops when I pull the trigger?"**
A: That's exactly how it works! When idle, see line pressure. When air flows (trigger pulled), the gauge shows your ACTUAL working pressure. Adjust the knob while flowing to dial in your spray setting—that's the number that truly matters for your finish

**Q: "Is this a true pressure regulator or just a flow control valve?"**
A: This is an inline flow control with integrated pressure gauge—perfect for spray guns where you need to control air delivery AT the tool. For traditional diaphragm-style regulation, check out our AR-02 model which offers that functionality.

**Q: "Will this fit my HVLP/LVLP spray gun?"**
A: Yes! Standard 1/4" NPT threads connect to virtually all HVLP, LVLP, and conventional spray guns. The swivel fitting lets you position the gauge for easy reading no matter how you hold your gun

**Q: "Will paint thinner or solvents damage the gauge?"**
A: No—the gauge features a real glass lens (not plastic) that's chemical resistant. Thinners and solvents bead right off without fogging or hazing. Many pros specifically choose this gauge because it stays readable through years of daily use.
