Description

The Graco Probler P2 Gun is engineered for demanding high-output spray polyurethane foam and polyurea applications. With its double-piston design, the P2 delivers over 300 lb (136 kg) of triggering force for smooth activation even under high pressure and tough job site conditions. The ergonomic handle and balanced layout make the Probler P2 easy to maneuver even in difficult spraying positions. Designed for plural-component coating systems, the P2 accommodates mix chambers in sizes AA (0.036″), 00 (0.029″), 01 (0.042″), 02 (0.052″), 03 (0.060″), 04 (0.070″), 05 (0.078″) for varied output and spray patterns. The standard flat spray pattern achieves about a 5 in (≈127 mm) width at 24 in from the target with the AA chamber, while larger chambers scale spray width as required. Built with anti-crossover design to prevent material entering the air piston and an air-purge mechanism for rapid cleanup, the Probler P2 ensures reduced maintenance time and increased uptime.

Frequently Asked Questions

Service & Support

Can the mix chamber be swapped on-site to change spray width?

Yes, the Graco Probler P2 Gun supports quick-change mix chamber inserts so you can switch between AA, 00, 01, 02, 03, 04, 05 sizes to adjust spray width and material throughput.

What distance should I hold the Probler P2 Gun from the surface for best results?

For optimum application, hold the Probler P2 approximately 18-24 in (≈45-60 cm) from the target surface and maintain a smooth overlapping motion—product documentation cautions against spraying over rising foam to avoid rough finish.

Does the gun handle extremely high pump pressures and long hose runs without performance drop?

Yes, the Probler P2 supports fluid working pressures up to ~3,200–3,500 psi depending on configuration, and the manufacturer notes that with hose lengths over 50 ft or high viscosity materials, higher pump pressures may be required to maintain proper mix.
