Chapin® Premier Pro XP Sprayer — 1gal Capacity

Viton-Sealed Professional Sprayer for Targeted Applications, 1gal

Seals that swell or break down after a season of pesticide and pH-adjustment use turn a sprayer into a leak risk right when consistent coverage matters most. The Chapin Premier Pro XP addresses that with Viton seals and industrial-grade internal components rated for a wide range of agricultural spray chemistry, in a 1-gallon format sized for targeted applications rather than whole-room coverage.

An adjustable nozzle covers everything from a fine mist for foliar feeding to a direct stream for spot treatment, and a pressure-lock shut-off holds line pressure between bursts so the operator is not re-pumping every few seconds.

Key Features & Benefits

• Viton seals — industrial-grade seal material resists degradation across a wide range of agricultural spray solutions for extended service life.
• 1-gallon poly tank — right-sized for targeted foliar applications and spot treatments without the bulk of a backpack sprayer.
• Adjustable nozzle — dials from fine mist to direct stream to match foliar feeding, pest management, or surface treatment needs.
• Pressure-lock shut-off — holds tank pressure between spray bursts, cutting down on how often the pump needs re-engaging.
• Wide-mouth tank opening — simplifies filling, rinsing, and switching between spray solutions.

Who Should Use This

Hydroponic cultivators and small commercial operations that need a dependable 1-gallon hand sprayer for foliar feeding and integrated pest management, particularly where a full backpack sprayer would be overkill for the treatment area, are the direct fit.

Frequently Asked Questions

Are the Viton seals compatible with pesticides and fungicides?

Viton seals resist a wide range of agricultural chemical formulations, including most pesticides and fungicides. Always check the specific product label for compatibility before using a concentrated or unusually aggressive formulation.

How do I maintain the sprayer between uses?

Flush the tank, pump, and nozzle with clean water after every use. Periodically lubricate the pump O-ring with a food-grade lubricant and inspect the seals for wear.

When is the pressure-lock shut-off useful?

Engage it during longer application sessions to hold line pressure between bursts, reducing how often you need to stop and re-pump. It also lets you set the wand down briefly without losing pressure.

Can I use this for pH adjustment solutions?

Yes, the Viton-sealed construction handles pH-adjusted foliar feeds and nutrient solutions without issue. Rinse thoroughly before switching to a different chemical type to prevent unwanted reactions in the tank.
