SPF Depot was founded in 2005 by Patrick Gililland, a fluid power engineer with a background in hydraulic systems and industrial equipment. Before launching the company, Pat worked extensively with Parker Hannifin products, covering southern Louisiana and specializing in extending the life of hydraulic components through remanufacturing and custom tooling—including projects supporting General Motors assembly lines.
In the early days, challenges were constant. After Hurricane Katrina devastated southern Louisiana, hotel availability disappeared. While servicing a job at the Weyerhaeuser paper mill, Pat slept in his truck just to complete the work.
That level of commitment would become the foundation of SPF Depot.
Everything changed after watching an episode of Holmes on Homes featuring spray foam insulation. Pat immediately recognized the potential of the industry and invested in a spray foam rig to begin applying foam himself.
It didn’t take long to spot a problem.
OEM parts weren’t holding up under real-world conditions.
So he did what engineers do—he fixed it.
Pat hard-coated a spray foam chamber, and the results were dramatic: three months of use with zero scoring, far outperforming standard OEM components.
Starting in his garage, Pat produced just 12 test chambers. Then came side seals. Demand grew quickly.
In its first year, SPF Depot generated $180,000 in revenue—all from a garage operation.
From there, growth accelerated:
Today, SPF Depot operates as a debt-free company, with:
SPF Depot is not a traditional distributor(v) but they have larger inventory levels than most "Distributors(n)" have.. While carrying major OEM brands like:
…the company also manufactures its own high-performance replacement parts—many produced by the same manufacturers used by OEMs.
In fact, SPF Depot stocks such a large inventory that even OEMs occasionally source parts from them.
SPF Depot was founded on one simple principle:
“If the customer wanted the part in two weeks, they would have ordered it in two weeks.”
That philosophy drives everything:
When OEM prices climb, SPF Depot develops alternatives—giving contractors a smarter option without sacrificing performance.
What began with just two products in 2005 has grown into a catalog of over 1,800 parts, supporting more than 14 spray foam guns in the global market.
SPF Depot also supplies parts to major industry players and continues to expand based on real-world contractor needs.
SPF Depot has expanded beyond parts into proprietary equipment, including:
In addition to equipment and parts, SPF Depot stocks trusted safety brands such as:
SPF Depot isn’t just another parts supplier—it’s a company built by someone who worked in the field, solved real problems, and refused to accept equipment that didn’t perform.
From sleeping in a truck after Katrina…
to building a debt-free, multi-million-dollar operation…
SPF Depot proves that innovation, grit, and customer focus still win.
Graco was founded in the 1920s by brothers Russell and Leil Gray. Graco started as the Gray Company, and its first product was an air-powered lubricator that was portable. This spray technology served a very specific purpose back then, but the company fully embraced the idea. Soon, other applications were developed. By the 1950s, Graco had developed the first airless spray gun. The company began selling worldwide. By the 2000s, Graco was leading the way with spray foam technology. Today, Graco carries a number of quality spray guns for a variety of contexts.
Graco spray foam guns are perfect for contractors, and they are made to streamline applications. They are easy to use and easy to clean. Most of them work with minimal prep and clean up, and they are compatible with most polyurethane foam and polyurea applications. Its most popular product is probably the Graco Fusion AP. In addition to the Graco Fusion AP, other popular models are listed here.
PMC spray foam guns are another popular option. PMC stands for Polyurethane Machinery Corporation, or Polymac for short, and this company got its start in 2007 as part of PMC Global. Although the company is relatively new, it is operated by individuals with vast years of experience in the urethane industry. This allows PMC to provide superior equipment and supplies to contractors. To this end, PMC has a comprehensive product line that includes a variety of spray systems. In addition to PMC spray foam guns, you can also purchase proportioning units, heat hose systems, transfer pumps and other support equipment.

Gusmer is part of the wider Graco brand, but its spray foam offerings are distinct. Gusmer joined the Graco brand in the early 2000s when the company was acquired through a business deal. Graco implemented such strategic acquisitions to expand and solidify its place in the market, and Gusmer was an apt fit. Unlike other spray foam systems offered by Graco, Gusmer systems are much more comprehensive. Gusmer offers a point-to-point electrical cabinet that is fully wired. This cabinet connects to the Graco hydraulic reactor, which ensures a strong, consistent performance.
GlasCraft is a company based in the United Kingdom, and it has a strong hold on the European markets. With 25 years of established production, GlasCraft focuses on quality plural component systems for spray or other types of dispensing. The company has been steadily seeking to expand its offerings, which is why GlasCraft is now proud to be a supplier of Graco equipment in the United Kingdom. Graco's operations are based in the United States, but through its partnership with GlasCraft, both companies have expanded their operations in a positive fashion.
Because of its position as a Graco supplier, much of what GlasCraft has to offer in terms of spray foam technology is from Graco. Popular options include the following.
Of all the companies listed, 3M has the widest range of products. 3M has always been dedicated to practical uses for scientific development. This may sound commonplace today, but it was an ambitious goal when the company was started in 1902. 3M started as a small operation in Minnesota known as the Minnesota Mining and Manufacturing Company. The original goal of the company was to mine for corundum. However, 3M never found corundum. Instead of admitting defeat, the company worked with the minerals it did find. In short, 3M worked to innovate, and with scientific and technical prowess, 3M managed to innovate its way to success.
Today, 3M is a Fortune 500 company, and it makes more than 60,000 products that are sold around the world. This includes a variety of spray foam products and other spray technology.
