28/400 PP Plastic Green Heavy-Duty Chemical-Resistant Trigger Sprayer

This trigger sprayer adopts the 28/400 thread specification, which is compatible with liquid storage containers with the same - specification bottle mouths. It has strong compatibility and can be widely used for liquid dispensing and spraying in scenarios such as cleaning, gardening, and industry. The main body is made of PP plastic, which is both durable and environmentally friendly, recyclable, and conforms to the modern green production concept. 

The liquid output per single press is accurately controllable, being 1.1±0.1ml per trigger, and it can output liquid stably, meeting the usage scenarios that require liquid output precision. 

The overall design adopts a white - green color scheme. The white main frame is simple and clean, with the green trigger and knob as accents, featuring high visual recognition. 

The trigger part follows the ergonomic design, and its curvature fits the natural bending shape of fingers. The force application during pressing is smooth, which can effectively disperse the hand pressure. Even with high - frequency operations, it is not easy to cause fatigue. It can be easily held with one hand to control the liquid output. The surface of the PP plastic material is smooth and has a solid touch, and it is not easy to slip or deform after long - term holding, ensuring the stability of use.  

As a "heavy - duty chemical - resistant" product, its PP plastic has undergone special process treatment, and it can withstand most common chemicals (such as cleaning agents, weak acid - base solutions, gardening nutrient solutions, etc.) and is not easy to be corroded and deformed. 

There is an "OPEN - TWIST" adjustment knob on the top of the spray head. Rotating it can switch between two modes: 

Spray mode: It sprays fine mist - like liquid, with a wide coverage area and high uniformity, suitable for scenarios such as disinfectant spraying and plant foliar fertilizer application, allowing the liquid to attach accurately and improving the effect; 

Stream mode: It switches to a concentrated water stream, with strong and directional liquid output, which can be used for rinsing stubborn stains and accurately supplementing water to plant roots, etc. One device has multiple uses and can meet various needs. 

The knob - type switch (with the "OPEN" mark) above the spray head can be rotated to the closed state when not in use, which can completely lock the liquid channel and effectively avoid the leakage problem caused by accidental squeezing.
