YAMATIC 4000PSI Short Pressure Washer Gun 1L Adjustable Foam Cannon, Stainless Core, 3/8" QC

The YAMATIC 4000PSI Short Pressure Washer Gun with integrated 1L adjustable foam cannon is a compact, high-pressure spray gun designed to produce thick snow-foam for safe, efficient vehicle and surface cleaning.

This compact foam cannon kit pairs a sturdy, short-body pressure washer trigger with a high-density stainless-steel foam core and a 1-liter adjustable bottle to deliver rich foam at pressures up to 4000 PSI. Built for hobbyists and pros alike, it fits most gas and electric pressure washers with 3/8" quick-connect fittings (not compatible with garden hoses, faucets, Sun Joe, or AR Blue Clean models). The design emphasizes control, reduced wrist fatigue, and consistent foam production for safer, more efficient cleaning.

How does the foam cannon create dense, clinging foam?

The YAMATIC cannon uses a high-density stainless-steel foam maker core that mixes soap and pressurized water to generate thick, long-lasting foam. The adjustable nozzle lets you change foam concentration and spray pattern for different cleaning tasks.

• Stainless-steel foam core for stable foam quality and durability
• Adjustable bottle and nozzle to tune soap concentration and spray angle
• 1L reservoir that holds enough solution for multiple cars or a single large wash
• Standard 1/4" quick plug improved for wear resistance and leak reduction

Will this gun attach to my pressure washer and hose setup?

The gun is designed for 3/8" quick-connect pressure washer inlets and works with many popular brands of pressure washers. It is not compatible with garden hoses, faucet fittings, Sun Joe, or AR Blue Clean units, so check your machine's quick-connect size before ordering.

• 3/8" quick connector inlet to prevent hose kinks and ensure a secure fit
• Compatible with many gas and electric units like Briggs & Stratton, SIMPSON, and Honda
• Not suitable for standard water hoses or incompatible brands listed in the product notes

How comfortable and durable is the trigger gun for longer cleaning sessions?

The gun’s short, snub-nose body and shockproof handle reduce leverage and hand strain, while an easy-pull trigger lowers the effort required to spray. Lightweight construction plus an ergonomic grip makes it easier to maintain control during extended washes.

• Lightweight trigger handle reduces hand fatigue during prolonged use
• Shockproof materials absorb impact and improve durability
• Compact form factor improves maneuverability around bumpers and tight areas

What maintenance and precautions should I follow?

Rinse the foam bottle and nozzle after each use to prevent soap buildup and clogging. Inspect the quick-connect fittings and the stainless-steel core periodically for wear, and store the gun dry to prolong seals and moving parts.

• Flush with clean water after every use to avoid residue and clogging
• Check quick-connect seals for wear to prevent leaks
• Store indoors or in a dry area to protect O-rings and metal components

Who is this for: The YAMATIC 4000PSI Short Pressure Washer Gun Foam Cannon is ideal for car enthusiasts, detailers, and homeowners who want a compact, easy-to-use foam system that produces thick, safe snow-foam.
