Graco 15B503 10 mm Nozzle – Product Details & Compatibility
Compatible Machines
The Graco 15B503 10 mm Nozzle is designed for high‑flow spray applications and is compatible with Graco airless texture sprayers and large‑output airless guns where a 10 mm nozzle is used.
- Graco texture sprayers requiring a 10 mm spray disc
- High‑volume airless systems used for heavy coatings, stucco, or knock‑down texture
- Spray rigs where OEM Graco 15B5‑series nozzles are specified
Product Overview
The Graco 15B503 10 mm Nozzle is a robust, OEM-grade spray tip designed for delivering large patterns and high throughput in demanding texture or heavy-coating applications. Built to handle thick materials and high pressures, this nozzle helps create broad, consistent spray fan patterns needed for applications like knock-down, orange-peel, acoustic textures or heavy coatings.
Key Features
- Large 10 mm orifice for maximum flow and high material transfer
- Durable construction suitable for abrasive or heavy-build coatings
- Supports wide fan patterns for texture spraying and coverage efficiency
- OEM Graco part — ensures reliable fit and performance in Graco spray systems

Usage Notes
- Ensure your sprayer can support a 10 mm tip — check the fluid section and pump pressure ratings.
- Flush the nozzle thoroughly before first use to clear any debris.
- Use proper spray pressure and angle to maintain an even fan and avoid thin spots or splatter.
- Clean the nozzle after each use, especially when using textured or thick materials, to prevent clogging.
- Inspect the orifice periodically for wear — large nozzles can wear faster under abrasive materials.
Frequently Asked Questions
A 10 mm nozzle allows for very high material flow and wide spray patterns, ideal for texture spraying or heavy coatings.
Only if the sprayer supports high‑flow tips and has a fluid section capable of handling thick materials and sufficient pressure.
Clean it after every use, especially when spraying textured or abrasive materials, and check for signs of wear or orifice damage periodically.
