Smith Performance Sprayers Contractor 1 Gallon Sprayer Model 190504 — Viton Seals, Brass Nozzles & Lockable Shut-Off

The Smith Contractor 1 Gallon Sprayer (Model 190504) is a heavy-duty, multi-purpose hand sprayer built for commercial cleaning, chemical applications, and lawn & garden use.

Compact yet rugged, this 1-gallon sprayer combines industrial-grade components with user-friendly features so you can apply disinfectants, herbicides, fertilizers, or cleaning solutions accurately and safely. Designed for frequent use, it pairs a durable pump system with replaceable Viton seals, a pressure release valve, and several nozzle options so you can tailor spray patterns to each task.

How does the sprayer stand up to harsh chemicals and repeated use?

The Contractor 190504 uses Viton seals in the pump and shut-off that resist degradation from aggressive chemicals, extending service life. Critical wear parts are engineered for easy maintenance so the unit stays reliable through repeated jobs.

• Viton seals throughout pump and shut-off for enhanced chemical resistance
• Nickel-plated brass poppet in the shut-off for strength and precise flow control
• In-line, easy-to-clean filtration to protect internal components
• Replaceable seals and parts designed for tool-free swaps when possible

What spray patterns and coverage can I expect for different jobs?

This sprayer includes multiple nozzle styles to cover a wide range of applications, from concentrated streams to fine foam. Adjustable poly and brass nozzles let you shift between stream and cone patterns, while flat fans and a foaming nozzle handle coverage and adhesion requirements.

• Adjustable poly nozzle — change from tight stream to wide cone
• Adjustable brass nozzle — durable, precision control for demanding liquids
• Two flat fan nozzles — even coverage for surface treatments
• High-performance foaming nozzle — improves dwell time for cleaning or sanitizing
• Compatible with TeeJet nozzles for additional options

What safety and comfort features reduce user fatigue and accidental spills?

The sprayer prioritizes operator safety and comfort with a lockable shut-off to minimize hand strain during extended spraying. A pressure release valve lets you safely vent pressure before opening the tank, reducing the chance of unintended discharge when refilling.

• Lockable shut-off reduces continuous squeeze fatigue during long tasks
• Pressure release valve releases tank pressure before opening
• Comfortable grip and 14" poly wand for reach without overextending
• In-line filter helps prevent nozzle clogs that can cause uneven spraying

How easy is the sprayer to keep clean and service when something goes wrong?

Maintenance is straightforward: the in-line filtration system is easy to access and clean, and many components are user-serviceable. Viton seals are designed for simple replacement to restore chemical resistance when needed.

• Accessible in-line filter for routine cleaning and clog prevention
• Tool-free or simple replacement of common seals and parts
• Durable materials that tolerate rinsing after corrosive use

Who is this for: The Smith Contractor 190504 is aimed at contractors, facilities managers, professional landscapers, and homeowners who need a compact but robust sprayer that handles cleaning, sanitizing, and aggressive agricultural or industrial chemicals. If you require reliable chemical resistance, multiple spray options, and safety features for frequent use, this model offers a balanced blend of durability, control, and serviceability.
