Product Overview

The Graco Fusion ProConnect 25P591 is a professional-grade spray gun body designed for ultimate rebuild speed and jobsite flexibility. Shipped without a mix chamber, it allows spray foam and polyurea contractors to configure the gun to their specific output needs by selecting the desired chamber separately.

Built on the durable Fusion Air-Purge platform, it delivers reliable performance and lower maintenance costs on high-production jobs.
