303 Products Foam Cannon Foam Gun for Pressure Washers — 2-Liter Reservoir, Adjustable Nozzle & Stainless-Steel Fitting

If you want thicker foam, longer coverage, and fewer refill stops during washing, this foam cannon from 303 Products is built for that purpose. It couples a large-capacity 2-liter reservoir with a stainless-steel, corrosion-resistant fitting and an adjustable nozzle so you can fine-tune foam output for cars, boats, trucks, home siding and more. The design focuses on durability, easy mixing, and efficient foam application so you spend less time scrubbing and more time finishing the job.

How does the 303 Foam Cannon improve my wash results?

The cannon increases contact time by laying down a thick blanket of suds that cling to surfaces, helping loosen dirt before rinsing. Consistent foam coverage reduces the need for aggressive mechanical scrubbing, protecting paint and trim while streamlining the overall process.

• Generates dense foam to lift and encapsulate contaminants.
• Large 2 L reservoir covers more area between refills.
• Even foam distribution minimizes streaks and missed spots.

What pressure washers and soaps are compatible?

The cannon works with most consumer and professional pressure washers that accept threaded foam attachments. It handles a wide range of vehicle and general-purpose detergents formulated for foam application—follow soap manufacturer dilution guidelines for best results.

• Fits common pressure washer wand fittings; check your model’s thread type.
• Use standard car wash or multi-surface detergents for foaming.
• Mix concentrate and water in the bottle per product instructions before use.

How do I adjust foam thickness and spray pattern?

Fine-tune foam density with the adjustable nozzle at the lance tip—turning the collar changes the spray angle and soap draw. You can also vary detergent concentration and water pressure to get the exact foam texture you prefer for different surfaces.

• Nozzle collar adjusts from tight stream to wide fan spray.
• Higher detergent concentration yields richer foam; dilute for lighter coverage.
• Pressure washer PSI influences foam cling and reach; consult your washer’s settings.

What features ensure long-term use and simple setup?

Construction includes corrosion-resistant stainless-steel hardware and a robust plastic reservoir designed for repeated use. The bottle fills and mixes quickly, and the assembly detaches easily for cleaning or storage—ideal for regular enthusiasts or seasonal deep-clean projects.

• Stainless-steel fitting resists rust in wet environments.
• Quick-disconnect style for fast assembly and breakdown.
• Wide-mouth bottle makes adding detergent and rinsing straightforward.

Who is this for? The 303 Foam Cannon Foam Gun is aimed at car enthusiasts, detailers, fleet managers, boat owners and homeowners who want a reliable, high-capacity foam applicator that simplifies washing and reduces repeat refills. If you value consistent suds, durable fittings, and the ability to control spray shape and foam strength, this 2L foam lance delivers a balance of coverage, longevity, and user control without specialized equipment.
