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.
