Great Stuff Pro 14 Foam Dispensing Gun — Silver aluminum body, adjustable flow (1/8"–3")

The Great Stuff Pro 14 Foam Dispensing Gun in silver is a lightweight aluminum applicator that lets you control bead size and reach tight gaps for cleaner, more accurate polyurethane foam sealing.

If you work on insulation, weatherproofing, or gap-filling jobs, the Pro 14 gun gives you steady, adjustable foam flow with improved ergonomics compared to straw applicators. Built for professionals but intuitive enough for experienced DIYers, this metal-bodied gun pairs with all Great Stuff Pro cans and helps you apply expanding foam precisely where it’s needed.

How does the Pro 14 improve foam control on a jobsite?

The Pro 14 includes a flow-control mechanism that lets you vary bead diameter from a fine 1/8 inch to a broad 3 inch stream, so you avoid waste and messy overfill. The metal trigger and lightweight aluminum body combine for smoother dispensing and reduced hand fatigue during repeated use.

• Adjustable flow for precise bead size (1/8"–3")
• Metal trigger for consistent squeeze and control
• Aluminum body keeps tool light without sacrificing strength
• Fits all Great Stuff Pro cans for quick attachment

Can I reach narrow or awkward spaces with this gun?

Yes — the Pro 14 is engineered to access confined voids and awkward angles that are hard to treat with disposable straws. The gun’s nozzle and controlled output reduce blowback and allow you to fill cavities, gaps around frames, and rim joist spaces more cleanly.

• Narrow nozzle profile for tight openings
• Precise bead control to prevent excess expansion
• Improved access for windows, doors, and piping penetrations

What makes this gun durable and suitable for repeated professional use?

The Pro 14’s high-strength aluminum housing resists wear and keeps the tool rigid under regular jobsite conditions, while the metal trigger delivers long-term reliability compared with plastic triggers. The design also simplifies cleaning and maintenance between uses to extend service life.

• High-strength aluminum body resists bending and damage
• Metal trigger withstands frequent use
• Compatibility with Great Stuff Pro cans keeps workflow consistent
• Easy-to-clean surfaces for longer tool life

How does it save time and reduce material waste?

By giving you granular control over bead diameter and dispensing speed, the Pro 14 minimizes over-application and cutbacks. Faster, more accurate application means fewer touch-ups and less foam wasted, improving both job efficiency and cost-effectiveness.

• Precise bead sizing reduces excess foam and trimming
• Quick attachment to Pro cans speeds setup and swaps
• Ergonomic feel cuts operator fatigue on long tasks

Who is this for? The Great Stuff Pro 14 Foam Dispensing Gun is aimed at contractors, insulation installers, and advanced DIYers who need reliable, repeatable foam application. If you require fine control in narrow gaps, durable construction for daily use, and compatibility with Great Stuff Pro cans, this silver Pro 14 gun is a practical upgrade from disposable options.
