MJJC Foam Cannon S V3.0

The cannon ships with a 1/4-inch quick-connect adapter, which is the standard fitting on most residential and entry-level commercial pressure washers in North America. The operating pressure range is 1,300–3,600 PSI. If your pressure washer uses M22 instead of 1/4-inch QC, a separate M22 adapter is required and is not included in this listing.

The 1.25 mm orifice is pre-installed and is rated for 1,600–2,200 PSI — the range most home electric and entry gas pressure washers fall into. The spare 1.1 mm orifice in the box is for lower-pressure machines at 1,300–1,600 PSI. If your pressure washer is above 2,200 PSI, the listing notes a 1.35 mm or larger orifice is needed and must be purchased separately.

Per the manufacturer's V3.0 upgrade list, the changes are: a redesigned foam orifice for thicker output, improved 360-degree spray control, a weighted pick-up tube to draw all the liquid from the bottle, a revised bottle and cap that attaches more easily to the cannon body, a redesigned fitting that no longer requires PTFE tape or glue to seal, and a new bottle shape that is less prone to tipping. The cannon is the third generation in the Foam Cannon S line; earliest verified-purchase reviews for the V3.0 listing appear in 2023, so multi-year ownership data is still maturing.

The body is plastic; MJJC has not published the specific polymer or resin code. The included 1/4-inch quick-connect adapter appears to be plated metal in product images. The valve body material is not disclosed in the Amazon listing or on the manufacturer's site. If long-term construction quality is a primary concern, an all-brass cannon (e.g., MTM Hydro PF22.2) is a different price tier.
