CHAPIN Tri-Poxy Steel Tank Sprayer 1180, 1-Gallon — 4-inch Wide Mouth, Brass Wand & Adjustable Nozzle

The CHAPIN 1180 is a 1-gallon tri-poxy steel tank sprayer with a wide 4-inch mouth, brass wand and adjustable nozzle built for reliable lawn, garden and home spraying tasks.

This compact, U.S.-assembled sprayer combines a corrosion-resistant tri-poxy steel tank, viton seals and a brass spray assembly to handle common fertilizers, herbicides and general household solutions. Its wide-mouth opening simplifies filling and cleaning, while the lock-on shutoff and adjustable nozzle let you switch between targeted streams and broader patterns without swapping parts.

How does the CHAPIN 1180 make mixing and filling easier?

The tank’s 4-inch wide funnel mouth lets you pour liquids and dry concentrates with minimal spillage and makes rinsing the interior straightforward. The metal handle and 1-gallon capacity keep the unit light enough to carry while still holding enough solution for small to medium jobs.

• 4-inch wide mouth for fast, mess-free filling
• 1-gallon capacity balances portability and run-time
• Wide opening simplifies internal cleaning and flushing

What spray patterns and controls are available for different jobs?

The CHAPIN 1180 includes a brass wand and a 4-position adjustable brass nozzle to choose stream, cone, or fan patterns. A brass shut-off with a lock-on feature prevents hand fatigue during extended spraying, and viton seals resist common chemicals to reduce leaks.

• Adjustable brass nozzle with multiple spray positions
• Brass shut-off with lock-on for continuous spraying
• Viton seals and gaskets for better chemical compatibility

Is this sprayer durable and suitable for lawn and garden chemicals?

The tri-poxy coated steel tank improves resistance to corrosion compared with bare steel, and brass fittings help avoid plastic-thread wear. It’s compatible with many household and garden solutions, though always check product labels and rinse the sprayer after use.

• Tri-poxy steel tank for improved corrosion resistance
• Brass wand and nozzle for longevity and reliable flow
• Made in the USA with global components and technical support

How do I care for and maintain the CHAPIN 1180?

Rinse the tank and pump after each use, especially when switching chemistries, and inspect viton seals periodically for wear. Store the sprayer dry and depressurized to extend component life and maintain reliable performance.

• Flush tank and wand with clean water after every use
• Check seals and nozzle for buildup or damage
• Store empty, dry and depressurized to protect parts

Who is this for: Homeowners, hobby gardeners and light-duty pros who need a dependable, compact sprayer for spot treatments, container gardens, patios and small lawns. If you want a portable, corrosion-resistant 1-gallon sprayer with brass components and an easy-fill design, the CHAPIN 1180 is built for those routine outdoor and household spraying tasks.
