Advanced Pressurized POLYURETHANE FOAM Dispensing Equipment
Optimized for your operations.
The SLUG Pro (Solventless Urethane Gun) was the first polyurethane dispensing system engineered to enhance worker safety by eliminating the need for flushing solvents.
This pressurized dispensing solution delivers controlled outputs from 6–60 lb/min. (3–27 kg/min.), making it well suited for pour-in-place applications requiring precision and repeatability.
More than a foam dispensing gun, the SLUG Pro is designed to improve operational efficiency, streamline workflows, and deliver consistent, reliable performance in demanding production environments.
Performs across a wide range of applications.
The SLUG® Pro is designed to support a broad range of polyurethane foam dispensing applications, providing the flexibility required across varied production environments. It is especially well suited for pour-in-place processes, where controlled output and consistent material delivery are essential to achieving repeatable, high-quality results.
Customized for your application.
Proudly American made, the SLUG Pro is produced at our global headquarters in Earth City, Missouri. Each unit is custom-built in-house by our technical service team to align with the specific requirements of the customer’s application. This hands-on, application-driven approach ensures precise configuration, rigorous quality control, and dependable performance in the field.
