What’s in a Spray Foam Gun Kit?

By Kevin Malone

Spray foam gun kits include a variety of components and accessories needed to apply spray foam insulation. What is in the kit may vary depending on the manufacturer and the distributor you work with, so you will want to discuss your needs with a reputable supplier to ensure you get the right equipment.

Intech Equipment & Supply can help you build a custom foam spray gun kit for your business to make sure you have everything you need for commercial and residential spray foam jobs.

Spray Foam Gun Kits

A typical  spray foam gun kit will include the following:

Spray Foam Gun

The spray foam gun is designed to mix and spray foam insulation materials under high pressure. You have several choices depending on the type of foam you plan to spray and how you want to purge the chemical residue. Air-purge guns, mechanical-purge guns, and solvent-purge guns are available.

Mixing Chambers

Most spray foam guns include mixing chambers where two-component foam insulation materials are blended before spraying. Mixing chambers wear out over time, so having a replacement chamber on hand can prevent extended downtime. Since chambers can usually be changed without major disassembly, they are one of the easiest components to replace so you can get your spray foam gun working again.

Nozzles and Tips

Most commercial spray foam guns come with interchangeable nozzles or tips to control the flow rate and spray patterns. Some spray foam guns allow for flexible presets, while others require swapping nozzles or tips to adjust patterns. Controlling the flow rate and pattern for precise application increases efficiency and reduces material waste.

Wrenches and Tools

A foam spray gun kit also includes the tools you need to maintain your equipment and install any field replacements. Different models of spray foam guns may need different tools for disassembly, assembly, and maintenance.

Cleaning Supplies

Keeping your gun clean is crucial to eliminate clogs and keep your spray foam equipment in optimal condition. Proper flushing and removing residue buildup inside hoses, nozzles, and mixing chambers are crucial. Spray foam kits generally include the cleaning supplies you need for continued operation.

Common Replacement Parts

You should also include some of the most common replacement parts you may need. For example, extra O-rings, spray tips and nozzles, gaskets, and filters for in-field replacement can help eliminate downtime and save a trip back to the shop.

Safety Gear

Spray foam chemicals can be hazardous, so most spray foam kits will include personal protective equipment (PPEs) such as goggles, gloves, safety glasses, and masks or respirators.


Your foam spray gun kit should also include all the documentation and user manuals you need to ensure you can properly set, operate, and maintain operations. Diagrams and instructions can make field adjustments and replacements easier.

Other Items

Spray foam gun kits can include things you find beneficial to have on the job. For example, some kits include canister heaters to pre-heat chemical materials in the tanks and stands to hold and stabilize the canister while spraying.
