Choosing the right spray gun can make the difference between a smooth spray foam or coating job and costly downtime. Graco has earned a reputation for high-quality, reliable spray guns, which is why we’re a proud Graco equipment distributor.
With several Graco spray guns to choose from, deciding which is the best one for your specific spray foam or coating project is a challenge.
Let’s break down the top Graco spray guns for spray foam and polyurea applications—including the Fusion FX, Fusion ProConnect (PC), Fusion Air Purge (AP), and the Probler P2—and help you identify the best tool for the job.
Fusion FX
If you’re looking for a modern upgrade to your Graco lineup, the Fusion FX hits the sweet spot. Built ground-up for today’s contractors, the Fusion FX brings a revolution in ergonomics, serviceability, and spray quality for both spray foam and polyurea applications.
- Smallest, Lightest & Most Balanced: At less than 3 pounds, the Fusion FX is 30% lighter and 9 times more balanced than the Fusion PC, reducing fatigue and improving control.
- Quick Access: Swappable mix-chambers and easy access via the removable air cap let you change materials or clean the chamber in seconds.
- Responsive Trigger & Ergonomics: This gun offers a 30% shorter pull than Fusion AP/PC guns, plus a redesigned handle and adjustable hand straps to boost comfort.
- QuickFlex Technology: Quickly switch between ClearShot (liquid-purge) and Air Purge modes with a piston swap—no need for a second gun.
- Smart Maintenance: Tool-less valves, ball-check manifold, lightweight filters, and modular hose manifold make it easy to maintain.
Fusion ProConnect (PC)
The Fusion ProConnect, commonly known as the Fusion PC, builds on the proven Fusion AP platform with a disposable ProConnect cartridge that replaces the entire fluid section. It delivers AP performance and ergonomics while revolutionizing maintenance. For contractors focused on uptime, efficiency, and consistent output, it’s the go-to gun.
- Instant Rebuild in Seconds: Rather than disassembling individual components, you can simply pop in a cartridge for a factory-level rebuild—no tools required.
- Proven Performance: The Fusion PC retains Fusion AP’s industry-leading air-purge mixing capabilities for reliable spray patterns across foam and polyurea applications.
- Cross-Over Containment Built-In: Integrated check valves in the cartridge prevent backflow and maintain consistent application and safety.
- Retrofit Capability: Upgrade your existing guns with a ProConnect conversion kit without buying a whole new gun.
- Ergonomic Design: Same handle, balance, and trigger feel as Fusion AP, minimizing retraining while maximizing comfort
- Ideal for Mid‑to‑High‑Volume Work: Designed for crews moving between jobs, needing a reliable tool that won’t hold them back.
Fusion Air Purge (AP)
The Fusion Air Purge, often called the Fusion AP, is Graco’s most trusted plural-component spray gun—perfectly balanced between durability, performance, and ease of use for both spray foam and polyurea applications. Its modular design and broad configuration options allow you to fine-tune output for different substrates and job sizes.
- Effortless Cleaning with Air-Blast Tip: The simple air-purge mechanism blasts out residual mix, preventing clogs and reducing daily cleaning time.
- Minimal Maintenance: Crafted with durable side seals and a robust mix chamber, the Fusion AP keeps downtime low.
- Tool-Free Mix Chamber Swaps: This spray gun has a quick-release fluid housing and hand-tightened front cap that let you change mix chambers without tools.
- Ergonomic Handling for All-Day Use: The Graco AP gun is lightweight and has a comfortable handle design to reduce fatigue during long pours or coating sessions.
Probler P2
The Probler P2 is Graco’s high-performance spray gun engineered for demanding spray foam and polyurea applications. Its unique double‑piston design delivers powerful spraying with minimal operator fatigue. This spray gun is a great option if you’re tackling rugged, high-output jobs and need a spray gun that’s both powerful and operator-friendly.
- Double-Piston Trigger Design: The Probler P2 offers over 300 pounds of triggering force for smooth, consistent fluid control.
- Lightweight & Ergonomic: Despite being bigger than other Graco spray guns, it’s easy to maneuver and has a balanced handle and responsive trigger to help reduce strain.
- Replaceable Mix Chamber Inserts: The user-friendly inserts make daily maintenance quick, minimizing nozzle swaps and downtime.
