Chemical Guys EQP_310 TORQ Professional Foam Cannon Max Foam 8, 32 oz Bottle Review (2026)

What this foam cannon is

This is Chemical Guys' TORQ Professional Max Foam 8 cannon, model EQP_310, which attaches to a pressure washer wand and mixes car wash soap with water to produce a thick layer of clinging foam across the vehicle before rinsing. Chemical Guys states the design produces about 30 percent thicker foam than earlier versions in its lineup, aimed at giving the soap more dwell time on the paint to loosen dirt before any contact washing begins. It ships with a 32 oz fluid tank that threads onto the cannon body, along with a fully adjustable nozzle for controlling foam thickness and spray pattern.

Pressure washer compatibility

Chemical Guys lists this cannon as compatible with pressure washers rated from 500 up to 3,500 PSI, covering most consumer gas and electric units sold for home use, with a stated maximum the manual advises not exceeding at 4,200 PSI. The company also specifies a minimum flow rate of 1.4 GPM, with 2.0 GPM recommended for the best foam output, and a ceiling around 5.3 GPM. In practical terms, this means weaker electric pressure washers near the bottom of that range will still work but tend to produce noticeably thinner foam, while gas units or stronger electric washers closer to the middle of the range get closer to the thick, clinging result the cannon is designed around.

Build quality and materials

Chemical Guys highlights solid brass components in the cannon's construction, which the company states resist corrosion and general wear better than the all plastic fittings found on cheaper foam cannons, alongside high quality plastics elsewhere in the body that are described as resistant to UV damage from repeated outdoor use. The tank connection uses what Chemical Guys calls a patented TORQ Threadlock System, intended to reduce wear on the threads from repeatedly screwing and unscrewing the bottle to refill it between washes, which is a common failure point on cheaper cannons that strip or crack after regular use.

How it is used

To use the cannon, the fluid tank is unscrewed, filled with warm water and one to three ounces of car wash soap, then reattached to the cannon body before connecting the whole unit to a pressure washer wand. Chemical Guys recommends rinsing the vehicle first to remove loose surface debris before applying foam, which helps the foam cling to the paint rather than immediately washing away dirt that could scratch the surface during the following hand wash. The adjustable nozzle lets the user dial in a wider spray for full panel coverage or a narrower stream for more concentrated foam on heavily soiled areas like lower rocker panels.

Who should buy this

This foam cannon suits owners who already have or are planning to buy a mid range to strong pressure washer, since Chemical Guys itself is clear that foam thickness depends heavily on the washer's flow rate and pressure rather than the cannon alone. It is a reasonable step up from bucket washing for anyone who wants to reduce direct contact scrubbing and the swirl marks that come with it, particularly for regular detailers who wash often enough to benefit from the more durable brass fittings. Owners with only a light duty electric pressure washer should temper expectations on foam thickness, since the cannon's output is ultimately limited by what the washer feeding it can deliver.
