TL;DR At 2.0+ GPM the EQP321 produces moderate foam — 30–60 second dwell on vertical panels per Amazon long-term verified-purchase reviews — adequate pre-soak coverage, not shaving-cream density. Multiple top reviews cite bottle-thread failure despite the TORQ Threadlock fix.
What it is and how it performs
Polypropylene-body foam cannon with a brass quick-connect for any standard 1/4" pressure washer lance. At 2.0+ GPM, community-confirmed output is moderate — reasonable pre-soak cling, thinner than top-tier stainless-body cannons at the same flow rate. Ratio knob makes a perceptible difference; fan pattern adjusts between narrow and wide. The TORQ Threadlock sleeve is a marketed fix for bottle-thread failure; multiple top Amazon reviews report the problem persists.
Who should buy this — and who should skip it
Good fit for home detailers at 1,500–3,500 PSI and 1.5+ GPM wanting a foam pre-soak step. Skip if your washer is below 1.4 GPM (a foam gun is the correct tool) or if multi-season reliability matters — the thread-failure pattern and 1–2 season lifespan favor alternatives. Amazon Add-On Item — requires a qualifying cart total.
Safety and environmental impact
Hardware with no chemical exposure pathway — health score 9.5 (Minimal Risk). Polypropylene body #5 recyclable; brass fitting is scrap-recyclable.
Frequently asked questions
What size pressure washer do I need for the Chemical Guys TORQ foam cannon?▾
The EQP321 works with gas or electric pressure washers rated 500–3,500 PSI. Chemical Guys specifies a minimum of 1.4 GPM water flow, with 2.0 GPM recommended for best foam output. At lower GPM machines (below 1.5 GPM) foam output will be thinner.
Does the Chemical Guys TORQ foam cannon fit any pressure washer?▾
It uses a universal quick-release fitting that connects to most standard 1/4" quick-connect pressure washer lances. It is not an M22 threaded connector — check that your pressure washer lance uses a standard 1/4" quick-connect before ordering.
How do I adjust the soap-to-water ratio on the TORQ foam cannon?▾
The brass ratio knob on the side of the cannon head adjusts the dilution. Turning it clockwise increases soap concentration; counterclockwise reduces it. Most users find the midpoint to upper-third of the range works well with snow foam soaps.
Can I use any car wash soap with the Chemical Guys TORQ foam cannon?▾
Yes — the cannon works with any foam cannon-compatible car wash shampoo and is not limited to Chemical Guys soaps. Soaps formulated specifically for foam cannons (low-dilution, high-sudsing) produce the thickest output.
Why did my TORQ foam cannon stop producing foam?▾
The most common cause is a clogged pickup tube or jet orifice from soap residue buildup. Disassemble the cannon and flush the uptake hose and orifice with warm water. Running clean water through the cannon for 30–60 seconds after each use prevents most clogging.
