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.
Typical Problems SPF Depot Focused on:
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. 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.
