DUSICHIN DUS-007 Snow Foam Lance Foam Cannon

The DUS-007 is rated for pressure washers up to 3,000 PSI and 6.0 GPM. Community reviews confirm adequate foam output at 2.0+ GPM on gas pressure washers. Sub-2.0 GPM electric pressure washers produce thinner coverage that works for pre-soak but not shaving-cream density.

It uses a standard 1/4" quick-connect fitting compatible with the common US-market consumer machines (Ryobi, Sun Joe, Karcher) without an adapter. M22-threaded lances require a separate 1/4" quick-connect adapter (not included).

The visible body is plastic with a brass-finish metal quick-connect coupling. The Amazon spec table reads 'Material: Alloy Steel,' but product imagery shows a black plastic foam-generator housing — the metal tag almost certainly refers to the coupling, not the body. Whether the brass-finish coupling is solid brass or brass-plated has not been independently confirmed.

The foam cannon itself, a 30 oz (900 mL) bottle, and a five-piece pressure-washer nozzle tip kit (size 030, different spray angles) for the pressure-washer wand. The nozzles are bundled accessories — they are not adjustments on the foam cannon.

One of 12 top Amazon reviews (Rainforest cache) reports a disconnect-valve rubber gasket that appears to have been misseated at the factory; the reviewer notes the gasket can be reseated. That is below the 3-distinct-reviewer threshold required to call it a documented pattern. No body-crack, thread-strip, or other fitting-failure reports surfaced in the top-reviews scan.

Run plain water through the cannon for 30–60 seconds at the end of each session to clear residual soap from the orifice and bottle. For storage, empty the bottle and keep the nozzle assembly and bottle separated to air-dry — recommended by a top reviewer with 20 uses logged.
