Professional-Grade Spray Performance
The Graco GX-7 5/70 Plural Component Spray Gun (SKU#142390) is a top choice for contractors who need high-pressure spray performance. It’s built for applying plural component polyurethane foam. That makes it ideal for spray foam insulation, concrete lifting, and roofing work. Its internal mix chamber, mechanical purge system, and balanced design make it both powerful and easy to use.
Performance and Design
The GX-7 5/70 is made for medium-output jobs. It sprays 14–16 lb/min (6.4–7.3 kg/min) at 1,000 psi. Its round pattern creates a 14-inch spray width from 24 inches away. This offers strong coverage and clean control. A built-in pattern knob lets users adjust output to match the task.
Its mechanical-purge system removes the need for solvent flushing. This helps reduce mess and keeps operations simple. Accurate material blending and smooth spray results give crews the control they need for reliable foam work.
Durability and Maintenance
The GX-7 5/70 is built with aluminum, stainless steel, and plated carbon steel parts. These materials help the gun stand up to tough job sites. Fluorocarbon O-rings add chemical resistance and extend the life of the tool.
A self-cleaning feature simplifies upkeep. Fewer parts and easy-to-access internals make maintenance faster. This reduces downtime and keeps jobs on schedule.
Compatibility and Application
This spray gun works with many Graco proportioners and heated hoses. It supports several mixing chamber sizes, so you can adjust the output as needed.
From foam lifting under concrete to large-area insulation, the GX-7 5/70 delivers strong, steady results. It’s a great tool for professionals who want long-lasting, no-fuss performance.
