SOLO 1-Gallon Handheld Pump Sprayer 430-1G — Viton® Seals, 45 psi Piston Pump

The SOLO 430-1G is a 1-gallon handheld pump sprayer built for durable, chemical-resistant performance with Viton® seals, a 45 psi piston pump, and four interchangeable nozzles for versatile spraying.

Compact yet robust, the SOLO 430-1G combines a high-efficiency piston pump with targeted chemical resistance to handle lawn, garden, farm and professional tasks. It’s designed to reduce pumping effort while delivering steady pressure and easy maintenance — a practical choice when you need consistent coverage, reliable seals, and flexible spray patterns.

How hard is it to pump and maintain pressure?

The 430-1G uses a piston pump engineered to reach up to 45 psi with fewer strokes than many similar sprayers, so you spend less time pumping and more time spraying. An integrated pressure relief valve prevents over-pressurization and can also be used to safely vent pressure before opening the tank.

• Piston pump design for efficient pressure build-up
• Automatic pressure relief valve that vents at 45 psi
• Manual pressure release option for safe opening and cleaning

Will it resist harsh chemicals and wear?

Key seal points use chemical-resistant Viton® material to extend component life and reduce failures when using aggressive solutions. The overall construction focuses on serviceability: a removable funnel top makes filling simple and a large secondary opening permits thorough rinsing and interior cleaning.

• Viton® seals in critical locations for improved chemical resistance
• Removable funnel top for spill-free filling
• Large secondary opening for easy internal cleaning

What spray patterns and accessories are included?

The sprayer ships with a four-nozzle assortment—adjustable, flat fan, jet stream, and hollow cone—so you can match spray pattern to task, from broad lawn coverage to targeted spot treatments. Nozzles are TeeJet-compatible and store onboard in a built-in compartment for quick access and fewer lost parts.

• Adjustable nozzle for variable droplet size and flow
• Flat fan for even coverage on horizontal surfaces
• Jet stream for long-distance spot application
• Hollow cone for fine misting and foliar coverage
• Onboard storage compartment keeps spare nozzles handy

How does it handle reach, control, and safety during use?

A 28-inch unbreakable wand and a commercial-grade shut-off valve with lock-on/lock-off deliver reach and ergonomic control for extended tasks. The shut-off valve locks for continuous spray and unlocks instantly to stop flow; the wand construction is durable to withstand field use and occasional impacts.

• 28" unbreakable wand for extended reach
• Commercial-quality shut-off valve with lock-on/lock-off
• Designed for reliable control during prolonged use

Who this is for: The SOLO 430-1G suits homeowners, landscapers, and small-scale agricultural users who want a compact sprayer that balances chemical resistance, efficient pumping, and adaptable spray control. It’s appropriate for weed and pest treatments, plant care, greenhouse tasks, and general site maintenance where dependable seals and quick nozzle changes matter.
