Foam Supplies Dispensing Equipment

Product Overview

Solvent-Less Urethane Gun: SLUG

Their patented Solvent-Less Urethane Gun – SLUG, for short – was designed, engineered and machined to give their customers a reliable, cost-effective, easy-to-use way to mix and dispense “pour and froth” urethane foam systems for a wide range of applications, across any number of industries.

No matter what type of need they have – from rotational molding to marine flotation, insulation/refrigeration, void fill, structural enhancement and more – the SLUG gets their foam exactly where they need it, in the most efficient, effective way possible. In fact, with the SLUG, they just point and shoot. What’s more, it’s durable, made from 2024 T6 aircraft aluminum. And it’s easy to maintain, offering various outputs, and eliminating the safety, disposal and environmental challenges associated with solvent flushing.


If they are looking for a simple, easy-to-use, cost-effective way to apply closed cell foam insulation, the Spritzer dispensing unit from Foam Supplies is the perfect solution.

Used in conjunction with their froth-based systems, the Spritzer unit is useful for a wide variety of manufacturing and construction applications. Just squeeze the trigger slowly for targeted control, or depress it completely to spray up to a rate of approximately six pounds per minute.

The Spritzer unit comes complete with standard 40-foot hose lengths, with a 1, 5 or 10-foot disposable whip. Custom hose lengths and a heat control are also available.

FLUSH Dispensing Unit

The FLUSH dispensing unit is one of the few – and currently the oldest – pressurized, “Pour-In-Place” dispensing units on the market. Similar to FSI’s SLUG unit, their FLUSH unit was designed, engineered and machined to give their customers a reliable, yet cost-effective, option for dispensing rigid polyurethane foam. Manufactured of 2024 T6 aircraft aluminum and other high-quality materials, the FLUSH unit is easy to maintain, offers various outputs, and can be used with both pour and froth-based systems.

With phase-outs and regulation of common urethane cleaning solvents and other flushing liquids over the years, the demand for dispensing units like the FLUSH has decreased drastically. As a result, FSI still offers support for customers who continue to use FLUSH unit technology, but they encourage their customers to convert to their SLUG unit system when possible.
