Foam Cannon Attachment for Pressure Washers — 160bar, PA Bottle, M22
$26.99
A standalone foam cannon attachment — PA bottle with adjustable concentration dial, rated to 160bar/2320psi. Connects via M22 quick-connect to most home pressure washers. The targeted purchase if you already have a functional trigger gun and just want to add foam capability.
Already Have a Gun? This Is What You Actually Need
The EPW04-002 is a complete kit — gun, foam bottle, nozzles. If your trigger gun is already working well, buying a full kit means paying for hardware you don’t need. This attachment is the foam cannon component only: PA bottle, adjustable concentration dial, M22 connection. Attach it to your existing gun’s M22 port and you have the full pre-soak foam setup without replacing what’s already functional.
Specifications
Foam Bottle
- Material: PA (polyamide) — chemical-resistant, handles concentrated car wash soaps without degrading
- Pressure rating: 160bar / 2320psi
- Connection: M22 quick-connect
- Dial: Adjustable concentration control for varying foam density
- Weight: ~1kg with bottle
Why PA Bottle Material Matters
PA (polyamide, also known as nylon) is chemically resistant to the soaps and detergents used in car washing. Cheaper foam bottles use less stable plastics that absorb concentrated detergents over time, which leads to discoloration, brittleness, and eventual cracking. PA handles regular soap exposure at pressure without those degradation issues.
Compatibility
M22 quick-connect fits the majority of residential electric pressure washers. Works with pH-neutral car wash soaps and most foam cannon formulas. Avoid strongly alkaline or acid-based detergents — these degrade PA material over extended use regardless of the manufacturer.
Not compatible with proprietary non-M22 connection systems. Check your gun’s foam port fitting before ordering.
Frequently Asked Questions
What’s the difference between this and the EPW04-002 kit?
EPW04-002 includes the copper spray gun, this foam bottle, and five nozzles — the complete setup for someone starting from scratch. This attachment is the foam bottle only, for buyers who already have a functioning gun and nozzle set and just want to add foam capability.
Can I use any car wash soap with this?
Any pH-neutral car wash soap works well. Foam cannon-specific soaps produce thicker, longer-clinging foam — regular car wash soap works but may be thinner. Avoid dish soap (degreaser content strips wax and sealants) and industrial alkaline cleaners.
