Frequently Asked Questions

Yes—this is a complete fluid-section. Install it per the Graco procedure, prime, and you’re ready to spray once leaks and pressure are checked.

Check your sprayer’s exact model and series (e.g., Ultra Max II 1095 / 1595, GMax II 5900/3900). If unsure, share your unit’s serial plate information to verify before purchase.

Hard priming, pressure drop, fluttering fan pattern, material bypass leaking, or frequent packings adjustments are common signs the pump/packings are due for replacement.

Basic hand tools and a torque-wrench (recommended) are typically sufficient. Follow Graco torque specs and use thread sealant where specified. Always depressurize and lock out power first.

Keep inlet strainers clean, use correct tip size, flush promptly after use, use pump preservative for storage, and replace packings/valves as needed per Graco maintenance intervals.
