Which Spray Foam Gun to Choose?

Graco Spray Foam Guns

Graco spray foam guns are known throughout the insulation industry for their innovative technology, durability, and efficiency in both residential and commercial spray foam applications. From the widely used Fusion Series to the performance-driven Probler P2, Graco continues to set the standard for spray foam equipment trusted by contractors and professionals worldwide.

Key Features of Graco Spray Foam Guns

Graco offers various purge methods including air-purge, liquid-purge (ClearShot), and mechanical-purge options to prevent clogging and maximize performance for any project or material.
The Fusion Series (FX, AP, CS, PC) includes ergonomic designs, lightweight builds, and advanced features like ProConnect cartridge heads for incredibly fast rebuilds and minimized downtime on the job.
With models like the Fusion FX, users benefit from the industry’s smallest, lightest, and best-balanced gun, making it a top choice for extended spray jobs or hard-to-reach areas.
The Probler P2 is built for high-output and demanding tasks, equipped with a double-piston trigger for smooth control and an anti-crossover system for consistent mixing.

Benefits for Contractors

Maintenance-friendly: Quick-change cartridge and mix chamber assemblies drastically reduce service time and let professionals swap components in seconds, boosting productivity and reducing costs.
Flexibility: Graco guns excel in both spray polyurethane foam and polyurea coatings, offering variable flow and pattern options to adapt to every job requirement.
Durability: Each model is constructed from robust materials to handle daily wear, harsh environments, and challenging projects.

Our Picks

Choose the Fusion FX if you need the lightest, most comfortable gun for high frequency, long duration, or demanding access spraying and if quick-change convenience is a top priority.
Choose the Fusion PC if you prioritize reduced downtime through easy fluid section swaps, variable output, and need a time-tested platform built on the proven Fusion air purge design.

Both models are highly respected, but the FX pushes innovation for those who value lightness and ergonomics—while the PC delivers simplicity, reliability, and hassle-free maintenance.
