Product Overview

The Graco CST521 RS Spray Tip is designed to deliver consistent, high-quality spray patterns for resin and gelcoat applications. Built for durability and precision, it ensures efficient material distribution across surfaces in demanding industrial environments.

Key Features

• Delivers a 10-inch consistent fan pattern for even coating
• 0.021" orifice allows controlled medium-to-heavy material flow
• Designed for industrial FRP applications
• Ensures smooth and uniform resin or gelcoat distribution
• Quick and easy replacement for RS spray systems

How It Works

The spray tip determines both the width of the spray pattern and the amount of material output. The “521” designation means a 10-inch fan width combined with a 0.021-inch orifice, making it ideal for covering large surfaces efficiently while maintaining consistent coating thickness.
