CHAPIN hose-end sprayer 16 oz Translucent White — 6-setting metering dial, brass mixing head

The CHAPIN G364 is a professional-grade hose-end sprayer with a 16-ounce concentrate tank, six metering ratios and an anti-siphon brass mixing head for accurate, hands-free dilution and spray coverage.

Designed for gardeners, landscapers and homeowners who want a reliable way to apply fertilizers, herbicides, pesticides or cleaning solutions, the G364 attaches to any standard garden hose and automatically mixes concentrate with water as you spray. Its transparent reservoir and precise dial let you measure and set the exact dilution without pre-mixing, while rugged components stand up to frequent outdoor use.

How do I set the dilution and start spraying?

Adjust the metering dial to the desired ratio, screw the sprayer onto a standard hose, fill the 16-ounce tank with concentrate, and open the water. The G364 uses an internal brass mixing head to meter concentrate into the water flow so you get a consistent spray without manually mixing.

• Choose from six preset mixing ratios for common applications.
• Translucent 16-ounce tank shows fluid level at a glance.
• Attaches directly to standard garden hoses—no adapter required.
• Open hose flow to begin automatic dilution and spraying.

What kinds of products can I safely use in the sprayer?

The G364 is intended for liquid concentrates labeled for hose-end application, including many fertilizers, herbicides, pesticides and household cleaning solutions. Always follow the chemical manufacturer’s label instructions and avoid incompatible or abrasive formulations to protect the sprayer and ensure correct application.

• Works with water-soluble liquid concentrates labeled for hose-end use.
• Do not use thick pastes, powders, or corrosive acids without checking compatibility.
• Flush the system with clean water after each use to prevent cross-contamination.
• Refer to chemical label for safety, PPE and use rates.

How much area will a full 16-ounce tank cover?

A full 16-ounce concentrate tank can spray up to about 100 gallons of mixed solution depending on the selected dilution ratio. Lower dilution settings deliver more concentrated product and therefore cover less total mixed-gallonage, while higher dilution settings extend coverage.

• Maximum theoretical output: up to 100 gallons of mixed solution from the 16-ounce tank.
• Coverage varies by dilution ratio and spray technique.
• Use the metering dial to balance concentrate consumption and coverage area.
• Transparent tank helps monitor remaining concentrate during large jobs.

What features improve durability and safety during regular use?

The G364 includes a brass mixing head for long-term reliability and a built-in anti-siphon valve that prevents backflow into the water supply. The sprayer’s robust construction and straightforward controls were engineered for professional and frequent residential use.

• Durable brass mixing head resists wear under repeated use.
• Anti-siphon valve protects hose and water source from backflow.
• Sturdy materials designed for outdoor exposure and repeated assembly.
• Clear reservoir and simple dial reduce application mistakes.

Who this is for: The CHAPIN G364 is ideal for landscapers, groundskeepers, plant professionals and homeowners who need a fast, accurate way to apply liquid concentrates directly from a hose. If you want to avoid pre-mixing, reduce measuring errors and complete larger spray jobs efficiently, this sprayer provides a durable, user-friendly solution that fits standard garden hoses and holds enough concentrate for extended tasks.
