Spraying Systems AA36 Brass Spray Gun – Adjustable Cone to Stream

The Spraying Systems AA36 Brass Spray Gun is a heavy-duty, adjustable spray valve designed for professional pest control and weed spraying applications. Its adjustable spray pattern allows operators to switch between a cone spray and a concentrated stream to suit different treatment needs.

Built with a durable brass body, the AA36 is a popular choice among pest and weed control professionals who need a dependable, serviceable spray gun. The valve is rebuildable, with replacement components available separately to help extend its service life.

The AA36 features a 3/4-inch female garden hose thread (FGHT) connection for attaching to a compatible hose fitting. Multiple tip orifice sizes are available to accommodate different spraying systems and flow requirements.

Features & Benefits

• Adjustable Spray Pattern: Adjusts from a cone spray to a straight stream for different application needs.
• Heavy-Duty Brass Construction: Durable spray valve designed for regular professional use.
• Rebuildable Design: Replacement parts are available to service the gun rather than replacing the entire assembly.

Selecting the Right Tip Size

Select your preferred tip (orifice) size when adding the gun to your cart. The appropriate size depends on your sprayer's pump output, operating pressure, and desired flow rate.

As a general starting point, we recommend:

• Electric Sprayers: Tip sizes 20 or 30.
• Gas-Powered Sprayers: Tip sizes 30 or 45.

These are general recommendations rather than universal fitment rules. Consult the tip specifications to compare flow rates at your intended operating pressure before selecting an orifice.
