Graco 15B990 Hopper Deflector Overview
The Graco 15B990 Hopper Deflector (also called a “guard, burp” / deflector) is a small but critical component used in Graco hopper-fed spray systems. It helps manage material flow and pressure, minimizing “burp” or splatter when pressurizing or cleaning the hopper.
Key Features
- Compact Design: Lightweight and low-profile part that fits directly inside the hopper assembly.
- Flow Control: Helps regulate material discharge during priming or pressurizing, reducing sudden spurts.
- Durable Construction: Made from molded material to withstand repeated use and high-pressure cycles.
- OEM Replacement: Genuine Graco part designed to integrate seamlessly into their hopper systems.
Benefits
- Cleaner Operation: By deflecting material during pressure changes, it reduces splatter and mess.
- Consistent Spray: A more stable flow helps maintain a consistent feed into the pump, improving spray quality.
- Less Maintenance: Helps protect other internal hopper parts by reducing the force of material ‘burping’ out.
- Cost-Effective: Inexpensive to replace, but can prevent larger issues and improve overall hopper-fed system performance.

Frequently Asked Questions
It deflects the material inside the hopper during pressure changes (such as priming) to prevent spurting or “burping” of the coating.
Replace it if it’s cracked, worn, or if you notice inconsistent material flow or excessive splatter from the hopper when pressurizing.
Not at all — it fits inside the hopper, and you typically just need to remove the hopper lid, insert the deflector, and reassemble.
While it's listed in some Graco hopper part‑lists (especially 6-gallon hoppers), you should verify using your sprayer’s parts diagram or manual to ensure that 15B990 is a specified component.
