28/400 28/410 28/410 PP Plastic Stream Sprayer Head Single Wall Trigger Sprayer for Kitchen Cleaning

A trigger sprayer is a manually operated pump mechanism designed to dispense liquids from a bottle in a controlled spray. Its core function is based on a positive displacement pump. When the trigger is squeezed, it creates a vacuum that draws liquid up through a dip tube. Releasing the trigger pressurizes this liquid, forcing it through a small nozzle.

The key feature of most sprayers is an adjustable nozzle, allowing users to switch between different spray patterns—typically a fine mist for broad coverage, a jet stream for targeted cleaning, or sometimes a foaming spray.

Commonly found on household cleaners, garden pesticides, and automotive products, trigger sprayers are valued for their cost-effectiveness, portability (requiring no batteries), and ability to minimize product waste through precise application. They are often made from chemical-resistant plastics like polypropylene, with seals chosen for compatibility with specific liquids, from mild detergents to harsh solvents.
